Numerical and experimental investigations have been carried out in order to study the effect of the poppet geometry on the flow-pressure characteristic of a direct acting pressure relief valve, which is equipped with a flow deflector for flow force compensation. A dynamic 3D-CFD model was built in ANSYS Fluent™, which is capable of simulating the interaction between the fluid flow and the poppet dynamics by means of mesh deformation and of a user-defined function (UDF). This model was applied to predict the flow-pressure characteristics of the valve for different spring preload settings and deflector geometries. The simulated curves were validated using experimental data acquired at FPRL (Fluid Power Research Laboratory) at the Politecnico di Torino, and an excellent agreement was found. The CFD model was then used to predict the effect of geometric parameters of the poppet, such as the cone angle and the position of the deflector. Finally, a 0D model has been developed in order to predict the flow forces; this model requires very few calibration points using 3D-CFD simulations, and can easily be implemented in lumped parameter simulation tools. It was found that this model leads to a satisfactory prediction of the flow-pressure characteristic of the valve.

Granite Reef Diversion Dam (Photo: SRP)
Salt River Project began releasing water from two reservoirs on the Verde River in recent days, sending water flowing into the normally dry Salt River bed in the Phoenix area.
The releases are occurring at the Granite Reef Diversion Dam to make room in the Bartlett Lake and Horseshoe lake reservoirs for additional melting snow into the Verde and Salt rivers watersheds, the result of the heavy snows that occurred late last month, SRP officials said.
Verde River water flows into the Salt River bed as it continues into Phoenix. The Salt River normally is dry through the Valley, with the exception of Tempe Town Lake, where dams hold water in place on the river bed. The downstream dam is designed to allow water to flow through when needed.
The water flow could be seen in areas of the river bed stretching to the Interstate 10 bridge in Phoenix Monday afternoon.
The flow forced the closure of McKellips Road between Alma School Road and Loop 202 freeway north of Mesa, and a portion of Gilbert Road between State Route 87 and Thomas Road.
Further crossings downstream could be impacted in coming days, SRP said.
According to a statement from SPR, Bartlett Lake and Horseshoe lakes will soon be reaching near capacity from snow melt, with only about 35,000 acre-feet of available space between the two lakes as of last Friday.
The total Verde River storage system was at 86 percent of capacity, up from 31 percent in mid-December. Horseshoe Lake was at 91 percent of capacity and Bartlett Lake 83 percent full.
Storage capacity along the Salt River was 59 percent full as of late last week. Roosevelt Lake, which holds about two-thirds of the water SRP stores, was at 51 percent – up from 40 percent on Jan. 1 and an increase of more than 150,000 acre-feet.
Salt River water storage reservoirs also form Apache, Canyon and Saguaro lakes downstream from Roosevelt Lake.

The Model DDX deluge valve is a hydraulic piston operated, mechanical type deluge valve. The valve is intended for use as a principal control valve in certain types of fire protection systems such as preaction or deluge. The valve can be reset externally after the operation. When the side chamber of the Reliable Model DDX Deluge Valve is depressed, the hydraulic supply pressure simultaneously affects the piston and pushrod assembly, as well as the underside of the clapper. The mechanical advantage of the lever multiplies the supply pressure’s resulting force pressing on the piston/pushrod, which is more than enough to maintain the clapper closed in the face of normal supply pressure spikes. The pushrod chamber pressure decreases instantly when a releasing device vents the chamber to the atmosphere through its exit.

All Ready for Exeter Flood Defense Scheme Phase 2
Construction work is about to begin on the second phase of Exeter’s flood defense scheme.
The work on a new flood embankment around Exwick playing fields will start next week (5 September).
Two out of the three playing fields will remain open during the works but the third playing field, which is closest to the health center, will be used to stockpile material and provide onsite facilities until the embankment is complete.
Although the construction is expected to be completed by spring 2017, the playing field will need to be kept out of use until it is restored to its previous condition.
Phase 2 of Exeter’s £32 million scheme, which started in July, aims to reduce flood risk to 3,200 homes and businesses. Work is progressing well, with 25,000 tonnes of material already being moved from Bromham’s Farm to Cowley field.
Investigation work has been carried out at the Quay to check the precise location of utilities such as power cables and gas pipes. Construction work on new demountable flood defenses will then start in November – avoiding the busy summer season. By Christmas, work will also have begun around Bonhay Road and Okehampton Road.
Phase 1 of the scheme got underway in 2014 and saw construction work just downstream of Exeter Quay. The Trew’s flood relief channel and the side spill weir at the top of the channel have been lowered.
This increased the flow capacity of the flood relief channel, which will help reduce flood risk during high river flows. The check weir at the downstream end of the flood relief channel will be removed later in 2016 to increase flow capacity further.
Exeter City Council and Devon County Council each contributed £3 million to the scheme. £6 million has come from government growth funding and the remainder is being funded by flood defense grant in aid.

In the pattern of the Longtan Power Station and the Three Gorges Power Station, China is set to start building another world-class hydropower station before the end of this year – the Xiaowan Power Station at Lancang River in Yunnan province.
The Xiaowan Power Station is the third-largest hydropower project after the Three Gorges Power Station at the Yangtze River and the Longtan Power Station in the Guangxi Autonomous Region. It will be the third terraced-hydropower station built along the Lancang River, reported the Hong Kong Ta Kung Pao of April 11. Bordering on Nanjian county of the Dali prefecture and Fengdu county of Lincang district in Yunnan province, the Xiaowan Power Station has been designed to have an electric generator installation capacity of 4.2 million kilowatts. It will be equipped with six electric generators, each possessing a generating capacity of 700,000 kilowatts. The construction of the Xiaowan Power Station will involve an investment of 21.3 billion yuan (US$2.57 billion).
Other hydropower stations: Also along the Lancang River, China has built the Manwan Power Station that has a 1.5-million-kilowatt electric-generating capacity. Additionally, construction is under way for the Dachaoshan Power Station that will have a generating capacity of 1.35 million kilowatts. Starting in 2001, China plans to build six more large hydropower stations along the Lancang River, which will complete a power network that consists of eight terraced-hydropower stations. Their combined electric-generating capacities will reach 15.55 million kilowatts, the article said. The State Power Corp. of China and three investing companies in Yunnan province jointly established the Lancang River Water and Power Resource Development Corp. in March. It is responsible for the planning, development and management of the water and power resources of the Lancang River. Longtan Power Station, to be built along Guangxi‚Äôs Hongshui River, will be second in size after the Three Gorges Dam but will require far fewer people to be relocated, officials say.

pumped water storage
Pumped water storage, also known as pumped hydropower, is a type of energy storage and power generating facility that pumps water to a storage reservoir during off-peak periods, and uses the stored water (by allowing it to fall through a hydro turbine) to generate power during peak periods. The pumping energy is typically supplied by lower cost base power capacity, and the peaking power capacity is of greater value, even though there is a net loss of power in the process.

EWEB draining Leaburg Canal
April 26, 2014
Maintenance work also planned for Walterville
The Eugene Water & Electric Board began dewatering the Leaburg Power Canal on Saturday morning, April 26, to perform maintenance on the power plant, canal and fish screen.
The shutdown of the Leaburg generating facility and power canal is expected to last about a week. During the shutdown, EWEB will divert very little water from the McKenzie River into the canal, which will cause the river level to rise downstream of the canal’s mouth.
During the re-watering period, expected to begin on or around May 3, the river level will gradually drop as more water is diverted into the canal.
The utility will complete similar repairs to the Walterville power plant, fish screen and canal beginning in mid-June.

The Federal Energy Regulatory Commission on Sept. 6 granted an April 2013 application from Baker County, Oregon, for a license to construct and operate the proposed Mason Dam Hydroelectric Project.
The project’s authorized capacity being licensed is 3.4 MW. The project will be located at the U.S. Department of the Interior, Bureau of Reclamation’s Mason Dam on the Powder River near Baker City in Baker County, Oregon.
The 173-foot-tall, 895-foot-long Mason Dam impounds the 2,235-surface-acre Phillips Reservoir, also known as Phillips Lake. Mason Dam was built on the Powder River by Reclamation to provide irrigation, water delivery, and flood control. Baker Valley Irrigation District provides for the day-to-day operation and maintenance of Mason Dam and controls flow releases at Mason Dam to the Powder River under an agreement with Reclamation.
The Mason Dam Project will use Reclamation’s existing reservoir outlet works, which will require modification of the discharge conduit to include a bifurcation to a new 105-foot-long, 72-inch-diameter penstock. The penstock will deliver flows to a new 40- foot by 28-foot powerhouse that will house a single 3.4-MW horizontal shaft Francis-type turbine-generator unit. The project will also require modification of the existing stilling basin to incorporate the project’s tailrace, and the construction of a new 0.8-mile-long, 12.47-kV overhead transmission line along Black Mountain Road to a new substation located within Idaho Power’s existing 138-kV transmission line right-of-way.
The project will be operated in a run-of-release mode, using flows that are released by Reclamation and/or Baker Valley for irrigation, flood control, or other purposes.

If the entire Odisha is battling with continuous power cuts amid rising temperatures these days, it is entirely because of the failure in hydro power generation.The total hydel power generation capacity of the state is 2,099 MW. In contrast, only 556 MW is currently being generated from seven hydel power plants in the state which is only a quarter of the total capacity.Despite the fact that there is no shortage of water in the reservoirs as compared to the water level this time last year, the production has come down.For example, the water level in Burla’s Hirakud reservoir on April 23 last year was 608.73 feet. On the same date, this year the water level of the reservoir was 612.83 feet.
According to energy experts, the present problem is arising because nothing has been done to dig up the reservoirs and increase their water holding capacity.Energy expert Bibhucharan Swain said, “Since the dredging of the reservoirs has not been done for a long time, the water holding capacity of these reservoirs is affecting the power generation.”On the other hand, Water Resources Minister Raghunandan Das said, “In terms of water level in the reservoirs, we are not in a dangerous position as the water level in our reservoirs has not reduced that much. But if the current heatwave continues for a few more days, nothing can be said as to what will happen.”Meanwhile, power generation at NTPC Darlipali Power Station has been affected. Giving the reason for the shortage of coal, the Energy Department said that efforts are on to address the problems of the consumers.

14th European Conference on Turbomachinery Fluid dynamics & Thermodynamics
In order to understand the flow characteristic of centrifugal pumps under air-entrained condition, a flow visualization test stand was set up. Pump performance, pressure pulsation and visualized flow behavior of a unshroud impeller centrifugal pump were analyzed under different air-water two-phase flow void. Performance at low flow rates is more sensitive to air content. Upon entering the air, the pressure pulsing frequency domain signal appear a lot of low frequency components. Using the example of air void fraction equal to 2%, axial frequency becomes an important frequency for all flow rates. With increasing inlet void fractions and decreasing flow rates, the bubbles increase in size and tend to agglomerate near the impeller suction side shroud at mid-chord and close to the pressure side close to the impeller outlet plane. The starting point of pump break down is related to a strong inward reverse flow that occurs in the vicinity of the shroud gap of the impeller and volute tongue area.


The Kuroshio turbine is a submersible power generator designed to be working against Kuroshio Current with an exclusively long system maintenance period. The long-term operational reliability of the shaft seal is one of the key factors in designing the Kuroshio turbine. Inspired by the ROV oil compensation system for thruster bearings and electrical junction boxes, a passive oil compensated shaft seal module, which is integrated with an oil compensator and shaft seals, is developed for a Floating Kuroshio Turbine (FKT). The passive oil compensator balances the surrounding seawater and the oil pressure, the internal spring evenly maintains the oil pressure slightly higher than the surrounding seawater to prevent water ingress. The new design of the passive oil compensated shaft seal module features high reliability, maintenance free and adaptability to any water depths, which will benefit and prolong FKT working endurance significantly. This study introduces different types of shaft seal and the concept of passive oil compensated shaft seal module. Then, a 1:25 scaled experimental model is established for several pressure tests and its performance is demonstrated.

Description for Gibe II Hydropower Plant (Ethiopia)
Gibe II hydropower plant is the second stage of the Gibe-Omo hydroelectric cascade which includes Gibe I and Gibe III (all in operation), Koysha (under construction) and Gibe V (planned). Gibe II has a total capacity of 420 MW and an energy production of 1’625 GWh/y.
The project was promoted by the Ethiopian Government to develop the hydropower potential of the Omo/Gibe river, a huge programme to improve substantially the power supply of the country.
Gibe II includes Africa’s longest hydraulic tunnel, more than 25 km long below the Fofa mountains, which requested major technical efforts and was one of the biggest challenges faced by our engineers to date.
The inlet area is located along the Gilgel Gibe river. A concrete gravity dam with an intake tower allows the diversion of a flow of about 105 m3/s inside the power tunnel, which delivers the flows through the penstocks to the powerhouse in the Omo river valley, the outlet area.
In order to face the silting of the reservoir, a desilting weir is foreseen upstream of the dam to create an impounding to store the sediments.
The dam is a classical concrete gravity structure with a straight axis. The spillway is located on the central blocks, including an uncontrolled overflow crest and a flip bucket (ski jump) energy dissipator device.
The bottom outlet, embedded in the dam body, is controlled by two sliding gates in series. This structure is especially designed, allowing the rising of the sill through stoplogs, to deal with the silting of the reservoir.
The project also included a river diversion canal on the right bank and two culverts in the weir structure close to the right abutment. Temporary upstream and downstream cofferdams completed the protection against flooding the dam area of permanent works.
In the outlet area we observe the surge shaft, a cylindrical structure with a throttle at the tunnel end. Two long steel penstocks end into a manifold with a bifurcation from two to four conduits, one for each turbine.
The power house is a conventional surface outdoor type with vertical axis units, located on the right bank of the Omo river. The structure is divided in five bays housing 4 Pelton turbines and the erection bay, while the control room finds place in the superstructure. The step-up transformers are located outdoor on a riverside deck.
The 400 kV lines are anchored in the excavation front behind power house, and connect the transformers outcoming lines cross the river going towards the switchyard.
- Gravity Dam ( H = 49 m, L = 140 m )
- Main Roads ( 65 km )
- Power Tunnel ( L = 25.8 km, D = 6 m )
- Penstocks ( No. 2, L = 1.1 km, D = 3.6 ÷ 2.8 m )
- Surge Shaft ( H = 95.5 m, D = 18 m )
- Outdoor Power House ( No. 4 Pelton turbines IP = 4x105 MW )
- 400 kV Switchyard
- Main Roads ( 65 km )
Examples of engineering challenges
One of the most evident examples of value engineering and design optimization is the construction of the power tunnel characterized by a wide range of geological conditions. The excavation was carried out by a double shield TBM having a boring diameter of 7 m, which erected precast concrete segment lining.
The lining, because of the relatively severe load conditions, was designed to bear the significant overburden reaching a maximum of approx. 1’400 m.
A second engineering challenge was the diversion of the river flows in the dam area, during the project construction, in the narrow and steep longitudinal section of the valley. The river diversion was achieved through a culvert (currently operating as bottom outlet) along with low blocks in the spillway structure which allowed a safe discharge of large floods up to 2’325 m3/s.

New power project coming up in KashmirMarch 20th, 2008 - 4:07 pm ICT by admin
Jammu, March 20 (IANS) The Jammu and Kashmir government is to construct a new hydropower project on river Chenab in the energy starved state, which has a potential of generating 20,000 MW of electricity. The 690-MW Rattle power project on river Chenab in Kishtwar district, about 230 km north-east of Jammu, will be built at a cost of Rs.30.85 billion, according to an official statement.
The state imports 1,400 MW of electricity to meet its demand of 1,800 MW.
Rest of the demand is met by the power generated by Chenani, Lower Jhelum and Upper Sindh power projects and royalty of 12 percent of the total generation of the centrally run projects, Uri and Salal.
Chief Secretary B.R. Kundal said the new project would help the state in overcoming the power shortage.
He disclosed this at a meeting in which the project was given a green light Wednesday evening.
“The government has decided to start work on Rattle project, at the basin of river Chenab, having the capacity of 690 MW. The construction work of the project has been handed over to Independent Power Producers (a private firm),” Kundal said in the meeting.
“With the completion of this project, problem of power shortage would be solved to a great extent.
“This will not only generate power but also provide employment to the youths of the state in general and of Kishtwar in particular,” Kundal said.

عنوان مقاله [English]
Bottom intake is one of the most appropriate systems for diverting discharge in steep rivers. Bottom intake with porous media is a new system of diverting discharge which can be replaced by bottom rack intakes. To investigate the hydraulic flow characteristics on diverted discharge of this intake, an experimental model was designed in which the inflow, diverted discharge and remained flow of porous media intake can be measured. In the present research, measurements of the diverted discharge were performed for different rates of flow, grain size distributions as well as surface slopes of intake with clear water. According to the obtained results, by increasing the inflow discharge, the rate of diverted discharge increases gradually and then reaches to a constant value. Any increment of the surface slope above the intake also decrease the relation diverted flow. It is found that the grain size of the porous media has a great influence on the diverted flow. By increasing the grain size diverted flow increases, too. Dimensional analysis and experimental results were used to estimate the discharge coefficient of porous media. Analytical analysis on experimental data shows that the discharge coefficient of porous media intake is about 0.1. Also an empirical-theoretical relation is proposed to evaluate the diverted discharge of this kind of bottom intakes.

Telangana: Kaleshwaram project across Godavari river reaches key milestone
KCR inaugurates Markook pump house in Gajwel constituency that pumps water into Kondapochamma Sagar
Rao inaugurated the Markook pump house in his Gajwel constituency that pumps water into Kondapochamma Sagar, a critical component of the world's largest multi-stage irrigation project.
KCR's spiritual guru Tridandi Srimannarayana Ramanuja Chinna Jeeyar Swamy attended and blessed the event.
Markook pump house lifts water into the 15 TMC capacity Kondapochamma Sagar reservoir that is said to irrigate 2.85 lakh acres of land besides supplying drinking water to 70 percent of the state including the twin cities of Hyderabad and
Kaleshwaram project involves Rs 1.05 lakh crore investment. The project consists of 22 pumping stations with 96 machines having a total of 4,680-megawatt capacity. The project with all its complex electro-mechanical underground works is being completed in four years.
With this new milestone, Godavari water has reached the highest level (618 meters) and 229 km away from Laxmi Barrage at Medigadda, the starting point of KLIS, which is aimed at making the Godavari a live river all through the year over a stretch of 274 km.
From Kondapochamma Sagar, water will be supplied through gravity to the hitherto arid lands.
Described as an engineering marvel, the project comprises 1,832 km water supply route, 1,531 km gravity canal, 203 km tunnel routes, 20 lifts, 19 pump houses, and 19 reservoirs with a storage capacity of 141 TMC. It requires nearly 4,992 MW of electricity to pump 2 TMC of water every day in the first phase.


Correct Answer - Option 2 : capacity/inflow ratio
(i) Trap efficiency of a reservoir is the ratio of total sediments retained by reservoir to the total sediments entering into reservoir (inflow sediments).
(ii) Trap efficiency of reservoir is the function of ratio of reservoir capacity and total inflow.
(iii) The reservoir capacity is inversely related to the amount of sediments deposited. As the time passes, rate of silting or rate of deposition of sediments reduces but amount of sediments deposited will be increased which in turn reduces the capacity of reservoir. Hence, trap efficiency also gets reduced.
Other factors affecting trap efficiency:
1. Size of reservoir and stream: A larger reservoir on small stream has less capacity inflow ratio and hence having higher trap efficiency.
. Velocity of flow of stream:
Higher velocity less deposition of sediments, lower is the trap efficiency.

Suki Kinari hydropower project is an 870MW run-of-the-river hydropower project being developed in Kaghan Valley, Mansehra district, Pakistan.
Suki Kinari Hydro Private Limited (SK Hydro), in which China Gezhouba Group holds a majority stake of 98%, is developing the project with an estimated investment of $1.96bn.
Ground-breaking ceremony of the project was conducted in March 2017, while operations are expected to be started by December 2022. The plant is forecasted to provide 3,081 million GWh clean electricity per annum to the national grid by 2022.
Suki Kinari hydropower project details
The Suki Kinari project is one of the biggest private-sector hydropower developments in Pakistan. To be monitored and supported jointly by the governments of China and Pakistan, the project is one of the highest priority early harvest projects within the China-Pakistan Economic Corridor (CPEC).
SK Hydro started the Suki Kinari hydropower project development in 2005 with the announcement of feasibility studies. The project will be handed over to the Khyber Pakhtunkhwa government, upon completion of 30 years of operations. It is being built on a build-own-operate-transfer (BOOT) basis and will take six years for completing construction.
The 3,106m-long reservoir will comprise a 54.5m-tall asphalt concrete rock fill dam featuring flexible concrete cutoff, spillways, power intake system, and other facilities.
The dam will comprise two radial-type gated spillways, with the lower one to be used for sediment flushing and handling flood flows and the upper one for normal reservoir water regulation.
Twin-barrel underground de-sanders will be constructed at the start of the headrace tunnel for removal of silt from water. The headrace tunnel will be 6m in diameter and 19.4km-long, while the two double-stage surge shaft will have a diameter of 770m.
Four penstocks, with a diameter of 2.12m and length of 160m, will deliver water from the reservoir to the underground cavern type powerhouse located 4.1km upstream Paras village.
The underground powerhouse will comprise four Pelton type turbines rated at 234MW each. It will also include four generators with a rated capacity and voltage of 218.37MW and 18kV respectively.
Two 4.1km-long D-shaped tailrace tunnels will be used for discharging the water back to the river.
