In this paper, for the first time, a set of guide-lines are presented for the systematic design of mixed-flow and centrifugal compressors and pumps with suppressed secondary flows and a uniform exit flow field.
The paper describes the shape of the optimum pressure distribution for the suppression of secondary flows in the impeller with reference to classical secondary flow theory.
The results show consistent suppression of secondary flows in all cases. The overall performance of the stage with the inverse designed impeller with suppressed secondary flows was found to be 5% higher than the conventional impeller at the peak efficiency point. Exit flow traverse results at the impeller exit indicate a more uniform exit flow than that measyred at the exit from the conventional impeller.


At the NEORSD Westerly Tunnel Dewatering Pump Station Project, several subcontractors are working to complete the exterior construction of the building. This spring and summer will be busy inside the new building with installation of the HVAC, process, and electrical systems. This complex project is continuing successfully towards startup activities starting late fall, and completion in May 2023.
The Station will mitigate overflows into Lake Erie by dewatering the Combined Sewer Overflow (CSO) Storage Tunnel and pumping the stored CSO to the Westerly WWTP when the plant has capacity to treat it. This Pump Station is a new 10,080 SF, 35-foot tall steel and masonry building under construction over top of the existing 46-foot diameter, 215-foot deep tunnel shaft. The project also includes installation of five massive submersible pumps (each producing over 525 HP and 6,250 GPM of flow) at the bottom of the shaft. Piping from each pump up through the shaft and into a new valve vault that feeds a new forcemain pipe to the Westerly plant is also included. Additionally, this project includes various general trade activities for construction of the facility. The project started in November 2020 and will complete in May 2023 at a cost of $27.3M. Upon completion, this project will be a major component of NEORSD’s Westerly Storage Tunnel Program that will control overflows at 2 permitted CSO locations along the Cuyahoga River to relieve local wet weather flooding AND reduce NEORSD’s CSO discharge volume into the Cuyahoga River by 277 million gallons per year, resulting in improved water quality in the river and Lake Erie.

Flow boiling heat transfer in small-sized channels employed in compact heat exchangers is attracting increasing attention with the progressing miniaturization in many industrial fields. Experiments have been conducted to investigate the heat transfer and the pressure drop in narrow channels (rectangular channels with 2×4 mm and 0.5×2 mm (width × depth)). The working fluid is deionized water. The flow rate is 100 up to 700 kg/m2s at exit atmospheric pressure. By means of video-camera, flow boiling phenomena were observed as well. Three flow patterns, i.e. bubbly flow, slug flow and annular flow, could be distinguished. Based on the present single-phase flow experimental results the flow boiling pressure drop was compared with the Lockhart-Martinelli correlation, and ±30% deviation from Lockhart-Martinelli was found.

Coomera River Channel Dredging Project
The Gold Coast Waterways Authority is improving access and connections to the waterways by dredging the Coomera River navigation channel from Sovereign Island to the Gold Coast Marine Industry Precinct at Coomera. Approximately 70,000 cubic metres of sand will be removed from the channel and beneficially reused.
- Reinstate the approved channel depth.
- Improved access and safety through the removal of shoaling.
- Easier access to Gold Coast Marine Industry Precinct and residential developments.
Reused sand will aid sand nourishment at northern Gold Coast beaches.
- A trailer hopper dredge and cutter suction dredge will operate in the channel which may restrict vessel access during the works period.
- The trailer hopper dredge will be regularly transporting dredge material from the downstream section of the Coomera River through the Seaway to the Narrowneck placement area.
- The dredge will display day shapes to indicate the passing side and will be contactable via VHF radio. Masters should reduce speeds and navigate with care.
- Water quality monitoring buoys will be installed adjacent to the navigation channel for the duration of the works.
- A cutter suction dredge will be transferring dredged material to the Coomera River Dredged Sediment Management Facility (CDSMF) from the midstream section of the Coomera River.
DREDGE AREA AND DEPOSITION SITE
Work starts on dredging Coomera River channel
- Dredging gets underway in the Coomera River is underway
- The $2.5 million project is scheduled for completion by June
A two-month dredging project to improve navigation in one of the Gold Coast’s most popular waterways is underway.
The $2.5 million project to deepen the Coomera River commenced on Wednesday 26 April.
The Coomera River is an important access way for commercial, industrial, residential, and recreational activity.
Approximately 35,000 cubic metres of sand removed from downstream of Sanctuary Cove will be used to replenish northern Gold Coast beaches.
An estimated 35,000 cubic metres of sediment unsuitable for the beaches will be piped to the Coomera dredged sediment management facility for processing.
Quote attributed to Gold Coast Waterways Authority Chief Executive Officer, Chris Derksema:
“Due to new ongoing funding for the Gold Coast Waterways Management Program, this will be first instance of dredging of the Coomera River channel as part of an ongoing regular maintenance regime,” Mr Derksema said.
“Work will focus on removing sand and sediment that has naturally built up over time in the navigation channel from Sovereign Islands to the Hope Harbour entrance.”
$50.4 million will be invested in construction and upgrade projects that will improve access to the Gold Coast waterways over the next four years.

THE ORANGE-RIET TRANSFER SCHEME
WATER TRANSFER SCHEMES IN THE MIDDLE ORANGE
The Orange-Riet transfer scheme is an extension of the Vanderkloof Canal system and involves a 112 km long canal which was completed in 1987. The canal supplies water from the main right bank canal at Vanderkloof Dam to the Riet river settlement near Jacobsdal which forms part of the Riet River Government Water Scheme. As a result of protracted droughts, the Kalkfontein Dam, previously the scheme's only source of supply, could no longer meet the needs of the total scheduled irrigation area.
An area of approximately 21 750 ha is now irrigated directly from the Orange-Riet Canal and includes the Riet River settlement, development along the Orange-Riet Canal, Scholtzburg and Ritchie Irrigation Boards and the lower Riet River Irrigation Board. The first 74 km of the canal has a capacity of 16 m3/s while the last 38 km has a capacity of 13 m3/s. Provision has been made for the increasing capacity of the canal to 24 m3/s. The Orange-Riet Canal is situated on a higher level than the right bank main canal near the Vanderkloof Dam. The Scheiding Pumping Station at the terminal of the main canal lifts the water 47 m high to the entrance of the Orange-Riet Canal.

Concrete dams are successors of masonry dams, however in the mid 90’s embankment dams became more attractive for investors and contractors because of their lower price and construction concept. In an effort to put concrete dams back on the pedestal, engineers came up with a new concept of construction of concrete dams – rolled compacted concrete. It is a completely new material, a combination of the benefits of both embankment dams and concrete dams. In the course of ‘Concrete Dams’ students will get knowledge about history of concrete dams, different types of concrete dams – gravity, buttress, arch dams, arch-gravity, rolled compacted concrete dams, construction elements, analysis of static stability, dynamic stability, the effect of temperature in concrete dams, design of appurtenant structures and more.
For more information on the organization of the course, take a look at the attached CV.


DEWA awards $15.8m Hatta consultancy contract to EDF
The contract, which is for the hydroelectric power station at Hatta Dam, covers design, hydro-geological, geological, environmental, geotechnical, and deep excavation studies
Dubai Electricity and Water Authority (DEWA) has announced awarding a consultancy contract valued at $15.8m (AED58m) to French company, EDF.
The contract, which is for the pumped-storage hydroelectric power station at Hatta Dam, covers design, hydro-geological, geological, environmental, geotechnical, and deep excavation studies, Dubai Media Office reported.
The contract terms also extend to consultancy on deep-water tunnel designs, the dam and hydroelectric power station, the tender for material supply, supervision of construction work, site installation, on-site testing, and commissioning.
HE Saeed Mohammed Al Tayer, managing director and CEO of DEWA, said: “The hydroelectric plant costs $522.7m (AED1.92bn). It is part of the Hatta Comprehensive Development Plan, launched by HH Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai.”
The power station project, with its total capacity of 250MW and a lifespan of 60 to 80 years, is reportedly the first of its kind in the region.
According to DEWA, it will implement the power station by utilising water stored in the Hatta Dam, which has a maximum capacity of 1,716 million gallons. The authority also has plans to draw water from an upper reservoir that it intends to build in the mountain, 300m above the dam level. The planned reservoir is expected to be able to store up to 880 million gallons.
DEWA explained that during off-peak hours, solar-powered turbines will pump water from the dam to the upper reservoir.
During peak-load hours, on the other hand, when production costs are high, turbines powered by the speed of waterfall from the upper reservoir will be used to generate electricity and will be connected to the grid.
DEWA is expecting the efficiency of power production to reach 90%, with a 90-second response to demand for electricity.


Flood warning active for Darling Downs rivers
A FLOOD warning is active for the lower Macintyre, Dumaresq and Weir rivers.
The Bureau of Meteorology issued its latest warning at 8.07am today, warning that moderate flood levels were rising in the Macintyre River at Goondiwindi.
Downstream of Holdfast there are minor to moderate flood levels being recorded along the lower Macintyre River.
The report states the Macintyre River at Goondiwindi was at 6.23 metres and rising.
Elsewhere on the Dumaresq River minor flood levels peaked at Bengalla on Wednesday evening and are now easing.
On the Weir River downstream of Giddi Giddi South there were minor flood levels easing at Jericho.
Minor flood levels were rising downstream at Mascot on the Weir River and Mungindi on the Barwon River.
Forecaster Kev Hutchins said the flooding was due to rain over the last few days.
He said there was no rain forecast at least for the next week.
Mr Hutchins said river levels were likely at their peak or falling.
It will be clear in Toowoomba for most of this week, with temperatures to be slightly above average on the weekend at 27 degrees.
On Monday and Tuesday it will be even hotter, with maximum temperatures to reach 29 degrees.


The student will be introduced to open channel flows covering the conservation of mass, the momentum and energy equations. This is followed with the formulations for steady gradually varied flows with/without lateral inflows/outflows. The student is further introduced to the design of channels for steady gradually varied flows with lateral inflows (side spillways) and lateral outflows (side weirs). The concept of flow controls is also covered. The development of the continuity and momentum equations for unsteady flows is introduced. Flood routing is also covered along with the concepts of the kinematic wave, the diffusive wave and the dynamic wave are covered. The concept of the characteristics and its application to the solution of the simple wave problems associated with sluice gate operations and dam break is also introduced. Sediment transport concepts and the resistance to flow due to bedforms in alluvial channels are also covered with the view of estimating the total sediment transport capacity and the friction factor for composite roughnesses. Design concepts for a stable channel is also introduced.

To speed up the construction of a temporary dam to block the Kakhovka reservoir after de-occupation, a temporary dam is planned to be designed.
The levels in all reservoirs are lower than they were last year at this time. The release of water from the Dnipro reservoirs is due to the need to provide consumers with electricity for the duration of the repair campaign. Today, Ukrhydroenergo has filed an emergency application to accumulate water in the Kyiv reservoir instead of using it.
In technical terms, Ukrhydroenergo's HPPs and PSPPs are ready for the autumn-winter period of 2023-2024.

Homes and businesses in Leeds City Centre stand to benefit from the new flood alleviation scheme which will make use of an Obermeyer moveable weir system which is designed to control water level in the river Aire as it passes through Leeds city centre.
The pneumatically-operated gates will replace fixed stone and masonry weirs at two locations in the city, Crown Point and Knostrop, and will allow water levels to be controlled during high flow events. This means the river can still be used by leisure craft and retain its aesthetic qualities without overflowing during peak rainfall. The gates, which are operated by compressed air and are designed to deflate when water levels rise, will be supplied by Dyrhoff Ltd, the Folkestone-based moveable weir specialists.
The gates chosen for the Leeds scheme are designed by the US company, Obermeyer Hydro. Dyrhoff has been the sole European agent for the Obermeyer gate system since 1996. The gates offer a number of unique benefits, including low maintenance and a low environmental impact, and are well suited to flood alleviation schemes. The Obermeyer gate system was developed in the USA in the late 1980s and Dyrhoff installed the first gates in Europe in 1997. To date Dyrhoff have supplied over 40 gates of this type in Europe, with fifteen being supplied at locations in the UK and France for navigation and flood control purposes in the last ten years, and a further twelve gates currently at the design stage for a major navigation and water level control project in Belgium.
The gates are operated pneumatically and provide automatic control of the upstream water level. They can be operated at any height from fully inflated to fully deflated. The patented system comprises a row of bottom-hinged steel gate panels supported on their downstream side by inflatable air bladders. By controlling the pressure in the air bladders, the upstream water level can be precisely adjusted within a specified control range and accurately maintained at user-selected set points.
A number of key parts, including the all-important steel gates, will be manufactured in the UK making this a flagship project for Folkestone-based Dyrhoff. The Leeds flood alleviation scheme and the gates are scheduled for completion in 2017.

Kishau Dam Project would utilize the water of river Tons which is a major tributaryof river Yamuna and forms boundary between Himachal Pradesh and Uttarakhandin most of its reaches in this region. The water stored in the Kishau reservoir shall be utilized for irrigation, power generation and to augment drinking water supplyfor National Capital Delhi.
The river at project site forms the boundary between Uttarakhad and Himachal Pradesh. The project site is near Samberkhera which is about 50 kms upstream of Dakpathar in Dehradun district Uttarakhand and about 10 km. upstream of existing Ichari dam. The nearest Rail head is Dehradun, the capital of the state and thenearest air field is at Jollygrant which is about 20 Km. from Dehradun. From Dehradun project site can be reached by road. Two lane metalled road is available up to Ichari dam site (Koti). From Koti to Sambarkhera (about 10 km.), single laneroad is existing.
This is a multipurpose river valley project which is proposed to create a grossreservoir capacity of 1824 Mm3. Not only the state but the whole country is suffering from the shortage of power and irrigation facilities, which are the mainsources for industrial and agricultural development. At present a lot of untappedpotential in terms of power and irrigation of the river Tons goes waste as which can be utilized for development of irrigation and power by constructing storage schemes on it.
Kishau Dam Project envisaged the construction of a 236 m high concrete gravity dam along with a 660 MW capacity power house across the river Tons, a tributary to the river Yamuna, for harnessing the vast monsoon flow of river Tons by storing and utilizing the regulated release thereof, for irrigation and power generation.


Garfield Water Works Rehabilitation
The project entailed the replacement of three (3) existing water storage tanks due to deterioration of the existing structures. The new 1.2 MG Belmont Hill Water Storage Tank enhanced pressure throughout the City. Boswell also prepared the engineering study, permit application and design of a new booster pumping station, and a 0.4 MG water storage tank to replace the existing facilities. The new facilities optimized use of the existing wells and minimized bulk purchase of water. The project included the installation and implementation of a system-wide Supervisory Control and Data Acquisition (SCADA) instrumentation system, which eliminated 24-hour manned controls. The project, funded under the New Jersey Environmental Infrastructure Trust Fund (NJEIT), had an approximate construction cost of $6 million.


The bypass channel has been constructed to take the canal flow from the Slad Brook and Painswick Stream around Dudbridge Upper & Lower Locks.
This is a separate channel from the Hydro-electric scheme, although they were constructed at the same time. The channel around the upper lock is open, as can be seen in the second photo.
The bypass channel also includes a fish pass, which is the separate small channel to the left within the main channel (bright green liner). At the end of the open section the channel then enters a 1.8m diameter pipe (top photo) which takes the flow past the lower lock. The water, with that from the hydro scheme, is discharged through an outlet under Dudbridge Road Bridge.
The third photo shows the bypass channel weir, where water enters the channel. The fish pass is to the left.

ISLAMABAD: The China Pakistan Economic Corridor (CPEC) project of Karot Hydropower Station is expected to be completed by early 2020, around nine months ahead of its completion date of December 2021, official sources said.
Roughly 25 per cent civil works of the project with installed capacity of 720 MW has already been completed and work on the remaining parts of the project is underway.
According to sources in Planning ministry, the project is being constructed at river Jehlum with an estimated cost of US $1420 million.
Financial close of the project was achieved in February, 2017 while land acquisition award has also been done.
Similarly, work for the construction of access roads, bridges, concrete batching plant, diversion tunnel and spillway is in process, the sources added.
The Karot Hydropower Project is a 720MW run-of-river project to be built on the Jhelum River, and is being developed by Karot Power Company (KPCL), a special purpose vehicle in which China Three Gorges South Asia Investment (CSAIL) also holds a shares.
The hydropower project (HPP) will have a reservoir storage capacity of 164.5m and is expected to create employment for 3,500 people, approximately 85 per cent comprising local citizens.
The Karot Hydropower Project will help to improve the dependability of the energy supply in the region by providing up to 3436 GWH of electricity per annum, the sources added.
Moreover, the project would also help the government to produce affordable, reliable, and clean energy for a longer period as all the energy generation methods are costly, whereas with Karot Hydropower Project; electricity will be generated at lower costs in comparison with other power generation technologies.
“In today’s age when Wind and Solar power generation technologies are still unable to produce cost effective energy, hydro power is still the most cost effective and suitable power generation technology available,” the source said.
With the passage of time power generation costs will be reduced and ultimately, consumers will benefit from this lower cost and more affordable electricity.

WAPDA executing Tarbela 4th extension hydropower project
18 June, 2016
LAHORE: The Pakistan Water and Power Development Authority (WAPDA) is executing Tarbela 4th extension hydropower project (T4) to generate 1,410MW electricity with its scheduled completion in February 2018.
However, an accelerated construction programme was devised with approval of the World Bank – the financer of the project – to complete the project by mid 2017 to benefit from the high water flow season of the year.
To execute T4 project, intake structure of tunnel No 4 was redesigned to fit generating machines. With a view to carrying out construction work to modify the intake tunnel in accordance with its new design, a concrete coffer dam was built in the reservoir. Height of the coffer dam – 1,512 feet above mean sea level – was ascertained in consultation with Indus River System Authority (IRSA) and keeping in view the water inflow pattern to the reservoir, where construction work would be continued until the reservoir level reaches 1,483 feet.
It was considered that the water level in the reservoir would raise to 1,483 by mid July and subsequently over flow the coffer dam. It is pertinent to mention that water from Tarbela can be released through spillways once the reservoir attains the level of 1,505 feet. Due to pre-monsoon rains and abnormal increase in temperature in the catchment areas, Indus River average inflows are 27,000 cusecs and 53,000 cusecs higher than the last five years’ average during May and June, respectively. Maximum capacity to release water from tunnel 1, 2, 3 and 5 is 190,000 cusecs, whereas current inflow is more than 250,000 cusecs. Consequent to the high water inflows, the reservoir will attain the level of 1,483 feet by June 19. Resultantly, the work on intake of tunnel 4 will have to be stopped due to overlapping of coffer dam. This eventuality is likely to adversely affect the ongoing works on T4 project, as completion of construction work on the intake of tunnel 4, which was planned to be completed by mid July 2016. It is pertinent to mention that construction work on intake tunnel of Tarbela 4th extension hydropower project was also suffered last year for about 4-6 weeks due to erratic flows and early increase in reservoir level and its late depletion in accordance with the IRSA indent.
The IRSA wrote a letter to the project authorities that in view of existing trend of inflows in the Indus River, it is expected that Tarbela may touch to 1,490 SPD level by June 30, despite the maximum release from the dam. This eventuality is likely to adversely affect the ongoing work on Tarbela 4th extension hydropower project.


Wetlands in the Barataria Basin were historically nourished by the fresh water, sediment and nutrients delivered by the Mississippi River and its many distributary channels. These sediment and nutrient inputs ceased following the creation of levees along the lower river for flood control and navigation. In addition, the construction of numerous oil and gas canals along with subsurface oil and gas withdrawal has exacerbated wetland loss in the area. From 1932 to 1990, the Barataria Basin lost over 245,000 acres of marsh. From 1978 to 1990, the area experiences the highest rate of wetland loss in coastal Louisiana.
The primary goal of this project is to create and nourish approximately 415 acres of emergent intermediate marsh using sediment from the Mississippi River. The proposed project involves dredging sediment from the Mississippi River for marsh creation by pumping the sediment via pipeline into an area of open water and broken marsh. The proximity of the project to the Mississippi River provides a prime opportunity to utilize this renewable river sediment resource. Additionally, tidal creeks will be created to improve marsh habitat value, and native intertidal marsh vegetation will be planted following construction.

The Arun-III hydroelectric power plant is a 900MW run-of-the-river hydropower project under construction in Nepal. Scheduled for commissioning by 2024, it will be the biggest hydroelectric facility in the South Asian country.
SJVN Arun-III Power Development Company (SAPDC), a wholly-owned subsidiary of India’s Satluj Jal Vidyut Nigam (SJVN), is developing the project on a build-own-operate-transfer (BOOT) basis. SVJN is a joint-venture between the Government of India and the Government of Himachal Pradesh.
SAPDC will operate the facility for a period of 25 years, excluding the construction period of five years, before transferring the ownership to the Nepal government.
Nepal will receive 21.9% of the electricity generated at the power plant as free power during these initial 25 years of commercial operations.
The project development agreement was signed by the Investment Board of the Government of Nepal and SAPDC in November 2014. The financial closure for the project, which is estimated to cost approximately £755m ($983m), was reached in February 2020.
The foundation stone for the Arun-III hydroelectric power project was laid in May 2018.
The Arun-III hydroelectric facility is being built on the Arun River in Sankhuwasabha district, Nepal. Arun is a tributary of the Koshi River in Nepal. The project site is located approximately 657km east of Kathmandu, the capital of Nepal.
Arun-III hydroelectric facility make-up
The Arun-3 run-of-the-river hydropower project comprises a 466m-long and 70m-high concrete gravity dam with four underground desilting chambers, a headrace tunnel, a surge shaft, an underground powerhouse equipped with four 225MW Francis turbine-generator units, and a tailrace tunnel.
The 466m-long, 11m-diameter diversion tunnel for the project will have a discharge capacity of 1,300m3/s, while the storage capacity of the dam will be approximately 13.94m3.
The design discharge capacity of the 11.74km-long, 9.5m-diameter circular headrace tunnel will be 344.68 m3/s. The headrace tunnel will be connected to the powerhouse through two steel-lined pressure shafts and four penstocks.
The powerhouse complex will be situated on the left bank. Each of the four vertical Francis turbines housed within the underground cavern will be paired with a 250MVA generator.
The transformer cavern will house 13 single-phase transformers, including one spare transformer, of 92MVA capacity each.
The electricity generated by the Arun-3 hydroelectric power station will be transmitted to Muzaffarpur in India through a 317km-long 400kV double circuit transmission line. SAPDC will construct the Nepal section of the transmission line that will stretch for approximately 217km from the Arun-3 facility to Bathnaha at the Indo-Nepal border.
A group of seven banks from India and Nepal agreed to provide debt facilities worth approximately £684 ($890m) for the project in February 2020.
Nepal-based banks Everest Bank and Nabil Bank will provide loans of approximately £104m ($135m), while Indian lenders including State Bank of India, Punjab National Bank, Canara Bank, Union Bank of India and Export-Import Bank of India have agreed to provide £580m ($755m).
Separately, the Government of India also approved an investment of approximately £150m ($192m) for the construction of the 400kV double circuit transmission line from Arun-3 to the India-Nepal border in February 2019.
The civil works for the project are divided into two lots. Jaiprakash Associates was awarded the Lot-1 civil works contract £128m ($172.6m) for the project in September 2017. The work scope includes the construction of the diversion tunnel, dam, intake tunnels, a part of the headrace tunnel, and the diversion tunnel gates.
Patel Engineering bagged the contract for Lot-2 civil works worth approximately £126.5m ($164m) in August 2018. The scope of work includes the construction of a part of the headrace tunnel, underground powerhouse, as well as pressure and surge shafts.
BHEL was awarded a contract worth approximately £58.5m ($80.5m) to design, engineer, manufacture, supply, erect and commission four vertical Francis turbines and generator sets at the power plant in May 2018.

Abstract: Siphon spillways provide a highly efficient control of flow with a small increase in the reservoir water level. Flow over the circular crest of a siphon is highly curvilinear. In fact, curved flows are common in hydraulic engineering applications. It is important to achieve a good understanding of curved flows. The purpose of this paper is to study the characteristics of curvilinear flow over a siphon spillway in the regain of a rounded-crest. The siphon structure has fixed upstream and downstream slopes. To investigate the curvilinear flow over the crest, theoretical analysis and numerical modelling were performed. The theoretical analysis was conducted to determine distributions of streamlines and the radii of curvature of the streamlines. The theoretical analysis uses curvilinear coordinates. The Dressler equation was used to mathematically study the flow at the crest regain. The Dressler equation is significant in flow analysis. It has been used to solve many hydraulic problems involving curved surfaces. Furthermore, we obtained discharge coefficient values for the siphon spillway from the theoretical analysis and compared them with existent experimental results. The flow field was obtained using Computational Fluid Dynamics (CFD) model for the case of submerged flow. The model results give flow velocities in three dimensions covering the geometry of the siphon spillway. For computations of multiphase flow velocity and pressure distributions, a range of Reynolds number values are considered. The computations use the RNG k-? model for turbulence closure. The RNG k?? model is proven to have high accuracy for simulations of turbulent flow, especially in domains with curved boundaries and wall boundary layers. The CFD model predictions are validated with using results obtained from momentum analysis and theoretical siphon model. The results from the current study shed light on such characteristics of the flow past the siphon crest as the discharge coefficient, velocity distributions, and pressure distributions. It is shown that the pressure on the siphon crest’s low surface is negative and therefore could lead to the occurrence of cavitation. The results show that the flow field computed by using the RNG k-? model matches well with the data from the momentum analysis. There is a reasonable agreement between the computed and theoretical values of distributed pressures and velocities.

The forging steel checkvalve can automatically open and close with the flow of the medium itself. It's also known as one-way valve, reverse flow valve, and back pressure valve, used to prevent the reverse flow of medium. Check valve is a kind of automatic valve. Its main function is to prevent the reverse flow of the medium, reverse rotation of the pump and the drive motor, and discharge of the medium in the container. The check valve can also be used to supply the auxiliary system where the pressure may rise above the system pressure. A check valve can be divided into swing check valve (rotating according to the center of gravity) and lift check valve (moving along the axis).
