Low pressure pulsations double-suction pumps, which can reduce the pump outlet pressure pulsations, are widely used in paper-making technique processes. To design the proper geometric sizes and improve the inner flow will reduce the outlet pressure pulsations. From the aspect of the pump hydraulic design, several optimized projects to lower the pressure pulsations are proposed, such as optimizing the arrangement of blades, changing the shape of the blades, changing the size of base circle and the shape of tongue of the volute, etc. The unsteady flows in different time and different impeller positions in every project have been simulated using the CFD software. The outlet pressure distribution is caught and described as the 2-D graphs of pressure pulsations versus time by EXCEL and MATLAB. By comparing the results of all optimized schemes, it has been shown that the stagger arrangement of blades, the increased diameter of base circle, the ladder tongue of volute, more blades of impeller all can reduce the outlet pressure pulsations of centrifugal pump.

Navigation Conditions at LaGrange Lock and Dam, Illinois Waterway. Hydraulic Model Investigation
ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MS COASTAL HYDRAULICS LA B
Pagination or Media Count:
LaGrange Lock and Dam are located on the Illinois River at river mile 80.2, 8 miles downstream from the city of Beardstown, IL. The model investigation was concerned with alleviating some problems of the wicket dam by replacing some of the wickets adjacent to the lock with a submersible tainter gate. The tainter gate would regulate the navigation pool under normal conditions and could be submerged to pass heavy ice flows. The tainter gate eliminates the need for using the wickets for pool regulation, therefore greatly reducing the raising and lowering of the wickets. The model investigation was necessary for evaluation of the effects of the proposed tainter gate on navigation conditions, water-surface slopes through the reach, and the potential for scouring of the channel downstream of the proposed tainter gate.

The OJSC Power Machines and the OJSC Zagorsk PSPP-2 have signed the contract for supply of turbine pumps for Zagorsk PSPP-2 (pumped storage power plant) under construction, with the cost about 3 billion roubles.
According to the project conditions, Power Machines will provide designing, manufacturing, model tests and delivery of four turbine pumps for four power units of the plant with capacity of 214 MW each. The equipment will be delivered to the customer within the period from 2009 to 2011. Besides that, Power Machines will carry out supervised erection works.
The power plant construction is planned to be finished in 2012.
Zagorsk PSPP-2 with design capacity of 840 MW it will be constructed near the existing Zagorsk PSPP. The new power plant is included into the general plan of arrangement of power facilities up to 2020 approved by the Government of the Russian Federation. The construction Zagorsk PSPP-2 is required to level up daily production schedules in the power supply system of the Moscow region by means of production and consumption of electric energy, regulation of active and reactive power and voltage in the power supply system.
This is the second pumped storage power plant of such great size in Russia. Power equipment for the first similar station – Zagorsk PSPP – was also supplied by factories of Power Machines in the mid 1980s.
A pumped storage power plant (PSPP) is a pumping and accumulating power plant whose principle of operation (accumulation) consists in transformation of the electric energy received from other power plants into potential energy of water. PSPP operates in a cyclic mode: at low power consumption in pumping mode, it feeds water from the downstream to the upstream channel of the plant, then using it in turbine mode during peak hours of loading.


The state government has given green light to the Brahmani and Banas linking project to supply additional water to the Bisalpur dam. According to the Public Health Engineering Department (PHED) and Water Resource Department (WRD) has started preparing a detailed project report (DPR) for the same. A survey to check for all the possibilities and time taken to implement the project will be conducted. The entire project is estimated to cost around Rs.6,000 crore and the DPR for the same will be completed in the next seven to eight months.
Chief Engineer, Islamuddin Khan explained, “After the completion of this project extra water will be supplied to Jaipur, Ajmer, Tonk, and Nagaur which is difficult due to the shortage of water in the Bisalpur dam right now. There will be an open channel constructed around Brahmani river and a tunnel will be dug in the mountain. As the river is located on a height, gravity will help water to flow into the tunnel and then supplied to the Banas river. After the completion of this project, Bisalpur is expected to never have any water shortage.”
After the submission of DPR, the entire project will take around three years to complete. Two weeks back, PHED also gave nod to increase the capacity of the pipeline from Bisalpur dam. The project is estimated to cost around Rs.288 crore and the tender will be invited in June. This project will take two years to get completed. After the completion of the project, it will supply an additional 170 MLD water to the city.
In the present scenario, rainwater flowing in the Brahmani River goes untapped. It gets mixed with the water of Chambal River, and it eventually meets Yamuna River flowing in Uttar Pradesh. According to an estimate, at least 355 million cubic meters of water can be utilized by interlinking the rivers every monsoon which otherwise gets wasted.

56th and Colfax Storm Drain Project
The Havelock Salt Creek Watershed has been studied and analyzed to determine deficiencies in the existing stormwater system. The drainage study completed a hydrologic and hydraulic analysis for both the minor events (5-year and 10-year) and major event (100-year) throughout the watershed. Several locations were identified for proposed projects to address the deficient drainage systems.
The stormwater system located along Colfax Avenue between Touzalin Avenue and N. 56th Street was determined to be undersized for the drainage area flowing toward the system. The existing system consists of storm sewer inlets and a 42-inch trunk line that cannot convey the flows for this area. This project will consist of analyzing two different alternatives to increase the capacity of the trunk line. Each option will be designed to 30% plans and then compared to determine the preferred alignment to proceed toward final design. Cost, feasibility, and effectiveness will all be factors in selecting the final design route.
- Replace the existing 42-inch pipe with a 5-foot x 5-foot concrete box culvert.
- The new box culvert will follow the same alignment as the existing system.

The Harbors at Haverstraw, a 544-unit residential building, is part of the waterfront brownfield redevelopment project along the Hudson River in the Village of Haverstraw. As part of the Harbors Project, the Joint Regional Sewer Board of Haverstraw (JRSB) required that GDC commit to upgrade the existing JRSB Dr. Girling Drive Sanitary Sewer Duplex Pump Station. JRSB sought capacity to handle future flows and the elimination of sub-standard pumping capacity when one pump was offline.
Tectonic advanced the design of the Girling Pump Station Upgrade in preparation for bidding, and assisted GDC with the bidding process. The design was approved by the JRSB and Rockland County Department of Health. The design included replacement of two dry pit mount pumps with larger 110 hp dry pit mount, new generator, controls and electrical service. Tectonic provided engineering construction support through the completion of construction and start up.
The design required careful consideration of bypass sequence and facilities to maintain operation of the existing pump station building and facilities during construction and startup of the upgrade.


In this paper, we use the parallel open source code parallelSPHysics based on the weakly compressible Smoothed Particle Hydrodynamics (WCSPH) approach to study a spillway flow over stepped stairs. SPH is a robust mesh-free particle modelling technique and has great potential in treating the free surfaces in spillway hydraulics. A laboratory experiment is carried out for the different flow discharges and spillway step geometries. The physical model is constructed from a prototype reservoir dam in the practical field. During the experiment, flow discharge over the weir crest, free surface, velocity and pressure profiles along the spillway are measured. In the present SPH study, a straightforward push-paddle model is used to generate the steady inflow discharge in front of the weir. The parallelSPHysics model is first validated by a documented benchmark case of skimming flow over a stepped spillway. Subsequently, it is used to reproduce a laboratory experiment based on a prototype hydraulic dam project located in Qinghai Province, China. The detailed comparisons are made on the pressure profiles on the steps between the SPH results and experimental data. The energy dissipation features of the flows under different flow conditions are also discussed. It is shown that the pressure on the horizontal face of the steps demonstrates an S-shape, while on the vertical face it is negative on the upper part and positive on the lower part. The energy dissipation efficiency of the spillway could reach nearly 80%.

D Type Horizontal Multistage Boiler Feed Pump
D type and DG type multistage water centrifugal pumps are used for the transportation of clear water without solid particles and liquids with physical and chemical properties similar to that of clear water. The temperature of the liquid tranported by D type pumps can not exceed 80℃. D type pumps are suitable for use in mines and urban water supply, drainage projects,water supply, drainage and firefighting of high-rise buildings or large buildings, cooling water circulation of air conditioning units, etc. The temperature of the conveying medium tranported by DG type pumps does not exceed 105°C. DG type pimps are applicable to the unit system and mother control water supply system of various capacity units in power plants. It is suitable for hot water applications such as , used as high pressure boiler feed water, urban and corporate heating systems, etc..
D, DG type horizontal multi-stage centrifugal pump adopts a two-end support structure and segment type housing.
The transmission of the pump is realized by coupling the elastic coupling with the motor.
The direction of rotation of the pump, seen from the body end of the pump, is clockwise.
D-type pump suction inlet is horizontal, DG-type pump suction inlet is vertically upward, and discharge outlet direction is vertical upward.
The pump stator consists of the suction section, the middle section, the spit section, the guide vanes, the packing body, and the bearing body.
The pump rotor is composed of shaft, impeller, balance plate, bushing and other components. Both ends are supported by roller bearings. The bearings are lubricated with grease.
The static joint between the water inlet section, the middle section and the discharge section is sealed with a paper pad by tightening the tension bolts. In order to prevent water from entering the bearing, a retaining ring is installed in front of the bearing, and an O rubber ring is installed between the shaft sleeves. Shaft seals at both ends are made of oil-immersed graphite packing. Sealing can be achieved by adjusting the tightness of the gland bolts. The temperature of the liquid transported by DG type pumps is higher than 80℃, so water-cooled packing gland is used.

CONSTRUCTION work has been completed on the South West Inverness Flood Relief Channel - the final phase of the £16 million Inverness South West Flood Relief Scheme.
The scheme has been designed to protect 600 homes at risk of flooding on the south side of the city.
A Highland Council spokeswoman explained: “The scheme is now operational and flood flows which would have normally passed through the Culduthel, Lochardil, Drummond and Hilton areas will now be diverted down the newly completed channel to outfall into the River Ness via the Holm Burn. There will be no change to the flows in the burns during normal conditions.
“The construction phase of the scheme started in the summer of 2010 at the River Ness and works have been on-going towards the upper intake on the Ault na Skiah Burn to the south of Fairways Golf course until now.”
Councillor Graham Phillips, chairman of the council’s Transport Environmental and Community Services said: “This is a major project for the city and represents a significant investment in flood mitigation measures to deal with exceptional weather flood events that we are increasingly experiencing.”
The council is also undertaking a £24.75 million project to protect 800 homes and 200 businesses in the city centre from flooding via the River Ness Flood Alleviation Scheme between Ness Bridge and Friars Bridge. Preparatory works are well under way in readiness for the construction of the flood defences.

The Lake James to Fontenelle Park Project is intended to remove and/or control flows in the Combined Sewer System which will reduce the frequency, magnitude and duration of combined sewer overflows.
The project is being constructed in two separate construction packages. The construction of the Lagoon Improvements is completed. Additional sewer construction and structures to control trash and water quality within the park have been built.
This project specifically is intended to expand the size and storage capacity of the existing Fontenelle Lagoon and accept additional stormwater for detention in the improved Fontenelle Lagoon. By providing additional storage capacity, stormwater flow rates and volumes will be reduced in the downstream combined sewer system, thereby reducing the size and cost of downstream facilities and reducing overflows to the Missouri River. By partnering with City Parks for this project, the Lagoon was expanded. Water quality in the Lagoon will be improved, and with the additional depth, it will be stocked with fish by Nebraska Game and Parks.

AbstractOptimal operation under uncertainty is a classical, albeit challenging, issue in reservoir operation. This study focused on the flexibility to tackle the inflow uncertainty of reservoir operation. Using the flexibility index, the inflow can be described as an adjustable interval range rather than a probability distribution, and all constraints should be satisfied within this interval. The flexible operation (FO) model is proposed by considering the flexibility index and hydropower generation simultaneously. If reservoir levels at starting and ending are fixed, the optimal hydropower output first increases and then decreases as the inflow increases. Consequently, the FO model can be solved by inputting either upper or lower boundary inflows. China’s Three Gorges Reservoir was considered as a case study. The results revealed that a trade-off between hydropower generation and the flexibility index exists. The reservoir water levels were lowered in the nonflood seasons to improve flexibility. The FO model can tackle uncertainty effectively, although it is slightly conservative in terms of hydropower generation. The proposed flexible method can be helpful in reservoir operation under uncertainty.

Analysis of Working Principles of High Temperature Check Valve
High-temperature check valve has a disc-shaped valve flap, which rotates around the axis of the seat, and due to the streamline design of the internal channel, it has less flow resistance than the butterfly check valve. It is suitable for low flow velocity and large diameter occasions where the flow does not often change. However, it is not suitable for pulsating flow, and its sealing performance is inferior to the lift type. The butterfly check valve is divided into three types: single, double, and multi-lobed, mainly divided by the valve diameter to prevent the medium from stopping or reversing, and to weaken the hydraulic impact.
High-temperature check valve is a check valve that has a valve flap that slides along the vertical centerline of the valve body
The internal thread check valve can only be installed on horizontal pipelines, and the valve flap of the high-pressure small-diameter check valve can be a sphere. The shape of the butterfly check valve body is the same as that of the globe valve (it can be used interchangeably with the globe valve), so its fluid resistance coefficient is relatively large.
The structure of the lift check valve is similar to the globe valve, and the valve body and valve flap are the same as the globe valve. The upper part of the valve flap and the lower part of the valve cover are processed with a guide sleeve. The valve flap guide is simple and can freely move up and down in the guide sleeve of the valve body. When the medium flows in, the valve flap is opened by the thrust of the medium, and when the medium stops flowing, the valve flap drops by itself onto the valve seat to prevent medium backflow.
In the straight through type butterfly check valve, the direction of the medium inlet and outlet channel is perpendicular to the direction of the valve seat channel. In the vertical lift check valve, the direction of the medium inlet and outlet channel is the same as the direction of the valve seat channel, and its flow resistance is smaller than that of the straight through type.
High-temperature check valve is a check valve that has a valve flap that rotates around the pivot inside the valve seat
The butterfly check valve has a simple structure and can only be installed on horizontal pipelines. It has a good sealing performance.
High-temperature check valve is a valve that has a valve flap that slides along the centerline of the valve body
The pipe check valve is a new type of valve. It has a small volume, light weight, and good processing technology. It is one of the development directions of bronze check valve and brass one way check valve. However, its fluid resistance coefficient is slightly higher than the rotary type check valve.
The compression check valve is a valve used to cut off boiler water and steam. It has the combined functions of a lift check valve and globe valve or angle valve.
In Carbo bronze valve factory, Our products are only assembled after the first product passes a random inspection every two hours to check the assembly performance of the employees. We have two casting production lines with an annual output of 80 million tons of blanks. All materials are tested by the laboratory, and the test reports are kept for three years for traceability.

Ningxia Shapotou Hydropower Project of Yellow River is a run-of-river hydro power project located in Ningxia of western China. More precisely, it is located in Yellow River, Zhongwei City. The Project Owner is Ningxia Shapotou Water Control Co., Ltd. The region the project is located in is a poverty-stricken minority region, and had a total population of 5.78 million in 2004, of which 819,000 living in poverty, the yar before the project’s inception. The region is a droughty and rainless area.
The total installed capacity is 120.3MW and the electricity supplied to the power grid is 578.022GWh yearly with a power density of 29.48W/m2. The electricity is connected to the Northwest Power Grid (NWPG) via the Ningxia Power Grid. The hydropower station consists of riverbed power station, two canal head power stations in the north and south main canal respectively.
The riverbed power station uses four bulb tubular turbine units, and the unit capacity of the turbines in the riverbed is 29MW. The canal head power station on the north main canal adopts bulb tubular turbine units and the power station on the south main canal adopts tube type water turbine-generator units, with a total installed capacity combined of 4.3MW (respectively 3.1MW+1.2MW). The project could replace partial electricity of NWPG and reduce GHG emission of the grid, dominated by fossil fuel power generation.


Construction on Stage 2A of the $24 million Ewen Maddock Dam upgrade on the Sunshine Coast will get underway by the end of this month (March) and will bring the dam in line with modern engineering design standards. Seqwater CEO Neil Brennan said the project was part of an ongoing dam improvement program to ensure all Seqwater dams continued to perform safely well into the future.
The project need was realised following a risk assessment of all Seqwater dams across
the SEQ region, including Ewen Maddock Dam, against the relevant dam
safety guidelines and latest engineering standards. Our assessments and ongoing
investigations have allowed Seqwater to prioritise dam upgrades.
The Dam Safety and Acceptable Flood Capacity Review for Ewen Maddock Dam recommended that dam safety upgrade works be completed in two stages. Stage 1, which was completed in 2012, consisted of installing pressure relief wells and constructing a partial height filter buttress to reduce the risk of internal erosion or heave failure in the foundation.
The second stage, Stage 2 upgrade works, are designed to reduce the remaining dam safety risks to a tolerable level. This second stage will be delivered in two sequential components, Stage 2A Embankment Works and Stage 2B Spillway Works.
The scope of the Stage 2A Embankment Works includes:
|Description of Required Upgrade|
|Lake Lowering||· Temporary works to lower the lake level to 60% Restricted Full Supply Level by installing 6 x DN710 HDPE siphons and associated infrastructure. The siphons inlet is located upstream of the spillway, lay on the left spillway abutment and discharge into the existing stilling basin. The estimated maximum flow rate of the siphons is 10m3/s.|
|Main Embankment||· Installation of an internal chimney filter to existing dam crest level and reinstatement of the outer earthfill zone to buttress the new filter.
· Construction of a reinforced concrete parapet wall along the crest of the dam, keyed into the new filter zone to raise the crest and provide the required additional flood capacity.
· Relocating or reinstatement of existing dam instrumentation.
· Recreation Facilities Improvements
The Stage 2A project has been awarded to Sunshine Coast-owned and operated construction company Hall Contracting and it is estimated to create up to 70 local jobs.
“This is a great outcome with a local contractor being awarded the work for the first stage,” Seqwater’s CEO Mr Brennan said.
Construction on the 18-month first stage (Stage 2A) is planned to begin at the end of March.
The dam’s water level will have to be lowered to about 60 per cent of its full supply to allow the works to proceed. Currently, both the Ewen Maddock Water Treatment Plant and Environmental Outlet Valve are being maximised to assist in the reservoir lowering needs.
Mr Brennan said “Seqwater has staged construction to reduce the amount of time water levels have to remain lowered.”
The second stage, Stage 2B, will involve strengthening the existing spillway and will be subject to a separate tender process. The timing of Stage 2B works is expected to be finalised by end of the year.

In December 1994, the Board of Managers initiated by resolution for a new project to establish an off-channel impoundment in the vicinity of sections 3 and 10 of Brandt Township, Polk County, MN. Construction of the impoundment started in 1999 and has been operational since 2001. The project site is on 960 acres is located 30 channel miles upstream of the Red River of the North. The total estimated cost of the project is $3.3 million.
The drainage area above the project is approximately 23.4 square miles. The project can store 4,505 acre-feet of water (5.2 inches of run-off) up to the primary spillway. The inlet structure is a 12′ x 8′ reinforced concrete box culvert and the outlet is a two-stage outlet with the lower stage a 48″ reinforced concrete box culvert. The embankment length is 5 miles and consists of approximately 750,000 cubic yards of earthen fill.
The Red River Watershed Management Board funded approximately 85% of the cost of Angus Oslo #4 Project construction costs. The MRSRWD paid approximately 15% with additional funding from a State of Minnesota Flood Damage Reduction Program Grant.


The dam vertical lift gate is one of the most important operational parts that regulate the high head water flow to power plants as well as satisfying the water needs for projects and areas downstream of the dam. Due to the high water levels in the dam reservoir, the gates are subjected to many hydrostatic and dynamic pressures that affect their performance and stability. Hence, it became necessary to study all parameters that may cause excessive pressures which may lead to reduce the gate performance efficiency or even cause failure. In the current study, the pressure distribution along the bottom surface of various gate lip shapes has been measured and presented as contour maps using Surfer software. The pressure fluctuation was observed to indicate the intensity of flow separation and reattachment which, in turn, causes a vibration that may threaten the stability of the gate or impede its proper functioning. The pressures in this study are expressed as a dimensional coefficient through the integration of pressure measurements at 8 points distributed over the bottom gate surface. The high intensity of pressure attachment indicates the critical condition for hydraulic design.

This two-part paper addresses the design of a U-bend for serpentine internal cooling channels optimized for minimal pressure loss. The total pressure loss for the flow in a Ubend is a critical design parameter, as it augments the pressure required at the inlet of the cooling system, resulting in a lower global efficiency. In this first part of the paper, the design methodology of the cooling channel is presented. The minimization of the total pressure loss is achieved by means of a numerical optimization method that uses a metamodel-assisted differential evolution algorithm in combination with an incompressible Navier-Stokes solver. The profiles of the internal and external side of the bend are parameterized using piece-wise Bezier curves. This allows for a wide variety of shapes, respecting the manufacturability constraints of the design. The pressure loss is computed by the Navier-Stokes solver, which is based on a two-equation turbulence model and is available from the open source software OpenFOAM. The numerical method predicts an improvement of 36% in total pressure drop with respect to a circular U-bend, mainly due to the reduction of the separated flow region along the internal side of the bend. The resulting design is subjected to experimental validation, presented in Part II of the paper.


In September 2002, when construction of the Siah Bishe pumped storage project resumed after 10 years, designers had to model the existing grouted diversion tunnel in the light of a new earthquake spectrum, as Amir M Horr explains
THE Siah Bishe pumped storage project is named for the village of Siah Bishe, which is located some 50km northwest of Tehran, capital of Iran. The project is close to the Khandavan tunnel, which is part of the pass road that crosses the Alborz mountains in the north-south direction and connects Tehran with Chalus city at the Caspian Sea.
The project is sited at elevations that range from about 1900m asl to 2400m asl. The upper and lower reservoir sites are situated in the Chalus Valley, which flows in the north direction.
Both reservoirs are to be filled by the discharge from the Chalus river and its tributaries. The catchment area of the upper reservoir is about 19km2 and that of the lower reservoir about 98km2. Both these catchment areas are of irregular and strongly mountainous character. The hill slopes are generally steep to very steep with no vegetation. Only small scattered lots in the river valleys are used for agriculture. Precipitation within the catchment areas varies widely, generally increasing with altitude. For the project, with its upper and lower dams, extreme precipitation and runoff are both very important.
To divert the water of the Chalus river during the construction period, diversion works consisting of cofferdams (diversion dykes) and diversion tunnels have been provided for both the upper and lower dams. In the final stage of the construction works, the tunnels will be transformed into bottom outlets for the upper and lower reservoirs.
The upper dam diversion tunnel, already built, is located in the right abutment with an inner diameter of 2.95m and the total length is about 605m. The lower dam diversion tunnel, also located at the right abutment, has an inner diameter of 4m with a total length of 700m. The discharge capacity of the lower diversion tunnel is about 209m3/sec, and that for the upper tunnel is 169m3/sec.
Both tunnels were designed and built ten years ago, based on the design loading conditions of the time. But since that time several moderate to sever earthquakes have occurred in the Alborz region and the design spectrum has to be updated, based on the new data.
Bottom outlet systems have been designed for both upper and lower dams to enable the discharge of downstream water in the case of a total shutdown of the power plant. They were also designed to draw down the reservoir for inspection and maintenance of underwater structures and in case of emergency. Design for the outlet systems – the intake structures, vertical shafts and outlets – has been completed. The water level in both reservoirs can be controlled to draw down the reservoir water in an emergency situation or control the reservoir filling rate at the time of initial impounding. The level can also be controlled to facilitate grouting operations, if they are required in future. In that case the reservoir level would be lowered to its minimum level to reduce seepage in the foundation where grouting is to be carried out.
The bottom outlet in the tender design satisfied US Bureau of Reclamation criteria for all practical purposes. The filling rate at the initial impounding should allow for monitoring of dam and reservoir performance.
To simulate the effects of the changed seismic wave propagation characteristic around the diversion tunnel liners, an advanced thermal-stress analysis based on the Laplace theory was used.
In the first stage, a steady-state thermal analysis was performed to simulate the distribution of high-pressure grouting. In the next step, a stress analysis using results from the thermal analysis and the structural two-dimensional plain strain elements was performed to obtain the pre-stress pressures induced by high-pressure grouting.
For the Siah Bishe project, a three-layered rock media with a depth of 250m was modelled (for material data see the table above right) using a fine-meshed damped finite-element model.
An impulsive wave was applied at the bottom surface of the media and wave propagation through the layers and the grouted areas around the tunnel liners was investigated. The symmetric boundary conditions were applied to both side faces of the model. A traction-free surface boundary condition was assumed for the top surface.
Plain strain structural solid elements were used to model the layered rock media and tunnel liner. The complex damping model used for viscoplastic materials was used to account for the dispersivity of the impulsive wave. Although it is almost impossible to model the cracks and joints in the rock media, a macro model with viscoplastic material characteristics was used to obtain seismic wave propagation around grouted tunnels. The accuracy of results for both the lower and upper dam’s diversion tunnels depends on the accuracy of the finite element models.

The Electricity Generation Company (Malawi) Limited (EGENCO) recently embarked on a project to divert a tributary that was depositing a lot of silt at the Tedzani intake pond. With the first heavy down pour at Tedzani and surrounding areas on Monday 19 November 2018, the river training project (diversion of the river) has proved to be a success. The silt, that ordinarily was destined for the Intake pond, was successfully diverted away downstream of the Tedzani Pond.
Commenting on the success of the project, EGENCO’s Chief Planning Engineer Archibald Kandoje said when they visited Tedzani Power Station during the heavy downpour, they witnessed firsthand the effectiveness of the newly constructed river training works.
“If it was not for the river training, all that silt would have made its way into the Tedzani reservoir. Money well spent,” Said Kandoje.
The project on dredging (removing of silt on the dam), expansion and river training (diverting a river that was bringing silt and trash at the pond) at Tedzani started in September 2017 and is expected to take 18 months. So far, the river training works have been completed and the expansion of the dam and dredging works are still on going.
The cost of the project is US$6,227,361.21.00 (about MK5 billion). It is expected that once the project is completed, the lost live storage capacity of the dam due to siltation will be reclaimed. The expansion of the dam and the reclaimed capacity means that EGENCO will be able to keep more water at the pond. This means that EGENCO will be able to run the machines at full capacity for longer hours during peak periods resulting in increased capacity available to the Single Buyer.
The expanded dam will also allow EGENCO to run the 19.5 MW Tedzani IV Hydropower Station which is currently under construction and hence increasing EGENCO’s energy generation capacity.


The main part of a new community hydro power scheme in Aberdeen has been lowered into place. It is hoped the Donside Hydro project – aimed at powering about 130 homes on the site of the former Donside paper mill, as well as selling energy to the National Grid – will be generating electricity later this month. Aberdeen Community Energy (ACE) is behind the project. The hydro power scheme will harness energy from the River Don.

Deep advantages with Framo cavern pumps
Land-based cavern storage is another key application for Framo cable-free electric submersible pumps. Larger Framo cavern pumping systems handle the actual transfer of oil, while smaller systems are used for seepage water service at underground storage facilities.
The Framo cable-free concept is as suitable for underground oil storage as it is for pumping at sea. With overpressure protecting both the power transmission system and the submerged electric motor, Framo cable-free electric submersible pumps can be safely installed within the hazardous zone.
Savings with a single pipe
Framo cavern pumping systems are designed with the endsuction
centrifugal pump at the end of a riser pipe with integral power transmission – as in seawater lift pumping systems – or suspended from the power transmission pipe. In either case, the caisson is used as the discharge pipe.
Discharging through the caisson instead of a separate pipe reduces weight, cost and the complexity of installing and maintaining the system. The lower part of the caisson is part of the pump delivery, as is a special suction adapter to segregate the suction and discharge sides of the system.
The same concept is used for high-capacity cooling water pumps in refinery installations.

[en] Efficient design of hydraulic structures such as weirs and bottom outlets requires a detailed description of the complex turbulent flows occurring on these structures. Compared to laboratory experiments, numerical modeling offers more flexibility and cost-effectiveness to test different designs. The non-hydrostatic 2D-vertical model presented here solves the RANS equations for incompressible flows in the vertical plane. It is based on the projection method for pressure-velocity coupling, while free surface tracking is conducted by means of the level set technique and Sussman’s velocity extension algorithm. It enables to predict accurately the flow pattern in the vertical plane and deals with multiple interfaces (jets, drops…). The solver has been validated for both steady and unsteady free surface flows, based on theoretical and experimental data. The paper will detail the application of the model to a pressurized flow and to a sloshing tank.
