The operational reliability of centrifugal pumps strongly depends on an adequate structural design of every single component. Therefore, the design process requires trustworthy information about the expected stresses and deformations.
The numerical evaluation of the deformations and the stresses in the impellers of multistage centrifugal pumps is the topic of this report. The loads acting on the impeller under operating conditions can be subdivided into structural and hydrodynamic components, which are considered by means of one-way coupled fluid-structure interaction (FSI) simulations. For the investigations, an exemplary multistage pump with a specific speed of nq = 30 has been chosen. The hydrodynamic pressure loads on the impeller are derived from the CFD solution for a single stage of the pump. These pressure loads are imposed on the impeller in the structural part of the simulation. In order to determine the resulting deformations and stresses of the impeller, static structural analyses are performed. Different operating conditions, i.e. flow rates and temperatures, are analyzed. Furthermore, the influence of structural impeller design parameters on the resulting deformations and stresses is investigated in detail. The thickness of the impeller shrouds as well as the fillet radii between the blades and the shrouds are considered as design parameters.


Turkey’s highest dam begins to hold water
Yusufeli Dam, a hydroelectric power plant built in on Çoruh Stream in Turkey’s northeastern province of Artvin, has finally started to hold water.
“We have completed the body filling of Yusufeli, the highest dam of our country. Our dam started to hold water,” President Recep Tayyip Erdoğan announced on Twitter.
Becoming Turkey’s highest dam with its 275-meter-high concrete wall, the facility will be able to meet the electricity needs of nearly 2.5 million people.
The structure also stands out as the third highest dam in the world’s “double curvature thin arch dam type” category.
The dam, which took nine years to build and includes a power plant with an installed capacity of 558 megawatts, is expected to amortize its cost in seven years.
The Yusufeli district, where nearly 7,000 people live, has been flooded to accommodate the dam project and the residents of the settlement were relocated to a new settlement that was determined by authorities.

The level control in hydraulic power plants on rivers is of great importance for their automation. The level is controlled in several aims. The most important is to maintain the fall height at his maximum in order to maximise the produced energy. In this paper, a new modelling method of the flow dynamics is presented. The obtained model is especially suitable for small friction losses situations where the level waves phenomena can not be neglected. Then, this model is used to design the state-observer control. Finally, a practical case is presented.

Piano Key Weir for Enlargement of the West Fork of Eno River Reservoir
The West Fork of Eno River Reservoir Dam is located near Hillsborough, North Carolina, USA. The earthen embankment dam provides an impoundment used by the town for water supply. The project was originally completed in 2000 with forethought by the owner for an expansion, which was anticipated in the original design. Currently, the design of that expansion to raise the reservoir level for increased water supply is underway. Following a detailed analysis of viable upgrades, a piano key (PK) weir (anticipated as the first to be constructed in the USA) was selected by the owner due to its effectiveness in meeting project requirements. Presented in this paper are the site-specific characteristics of the existing auxiliary chute spillway, the proposed PK weir, and additional modifications to the chute. This paper also presents site-specific information including the existing auxiliary chute spillway, the new PK weir, and additional modifications to the auxiliary chute. The results include the comparison of four PK weir hydraulic design methods for sizing the spillway. Details and results of a CFD model are also included. Finally, additional significant design considerations are presented, which include anticipated hydraulic conditions in the downstream chute and identified existing structure deficiencies; estimated spillway design flood hydraulic force distributions taken from the CFD model; the PK key weir stability summary; and other important project aspects including embankment modifications and seepage control measures. It is anticipated that this project will be of interest to those concerned with dam safety and will further encourage the consideration of PK weirs in the USA.

IV. Distinguishing features and characteristics in technological aspects in the construction of Liuxihe Hydropower Station in Guangdong Province
The Liuxihe Hydropower Station has been one of the key engineering constructions listed in the state-run first Five-Year plan. It has also been one of the great practice of the State-run hydropower construction, following the building of Fuziling, Guanting, Gutianxi first phase, first stage of cascade development, Shizitan, Meishan and Shangyoujiang. It is the seventh median-sized hydropower station after the founding of New China, being a multi-purpose project mainly for the exploitation of water power resources. The river basin planning work was started on September 1955, while the preliminary design was begun conducting on January 1956. The said project was begun constructing on August 1956, the first power set was put into operation on August 1958 and all four power sets were put into commissioning in the same year.
1. The characteristic features of the project
The river bed at the dam site of the Liuxihe Hydropower Station appears in V-shape. All mountain slopes are steep and precipitous. The bed rock is of granite with simple geological structure. The dam has adopted a variable radius and variable central angle as well as variable thickness circular arc, concrete double-curvature arch dam. The characteristic ratio of bottom width and dam height is B/H = 0.283, being the first thin arch dam ever adopted in China during that time.
The overflow spillways are provided at the arch dam crest, which is the first case of flood spilling at the arch dam crest. There are seven bays of spillway, without the provision of gates at the dam crest, being of the free surface spilling type. The sky jump energy dissipater with apron sills at high and low levels are installed at the end of spillway, thus making the water flow mutually collided in open air for energy dissipation. In later stage, for the sake of convenience in flood dispatching, mitigating the erosion of dam foundation due to flood discharging from surface spillway, a flood discharge tunnel was built on the right bank in addition to other discharge facilities, thereby making possible to adopt a combined flood discharge scheme. The flood discharge tunnel is mainly responsible for flood release associated with the flood discharge function of the spillway on the arch dam crest.
In 1969, a flexible rubber dam was additionally built on the weir crest of the spillway, acting as a controlling gate to retain flood, which could be used for power generation during the tail period. Hence, it is possible to elevate the pool level 2 m, thus increasing power generation benefit.. Owing to the instability of air pressure within the collapsible rubber dam bag, causing surplus discharge and endangering the downstream flood control safety, the flexible rubber dam was dismantled in 1987.
The reservoir was built without reserving a bottom outlet for reservoir emptying.A water depth of 30 m still remained in front of the dam, the corresponding reservoir capacity of roughly 45 million m3 failed to be emptied. Once the safety problem of the arch dam encountered, it will be more difficult to strengthen the project or to take any remedy measures.
2. Characteristic features of the project construction
The main engineering quantity of the Liuxihe Hydropower project are: earth and rock excavation work 680,000 m3, earth-fill work 250,000 m3, concrete placement 187,000 m3. As the hydro-project is located in the narrow gorge, the general layout of the construction site is more difficult.
A semi-automatic concrete mixing plant is employed for dam concrete. Light rail concrete transfer truck and 9-ton gantry crane., etc. are adopted for mechanized construction. The effective period of construction for concrete placement reached nearly 12 months. The average monthly volume of placement reached 11,000 m3, the peak monthly placement being 20,600 m3. The coefficient of non-uniformity is 1.8 --1.9. The fourth grading concrete is used for dam proper, the max. grain size of aggregate being 150 mm. The #140 - #250 concrete are used for different parts of the dam project. The design criterion of concrete is 120 day-strength, combined materials additives, plasticizing agent, stone block buried are used in concrete mixing. Attention is fully paid on lowering the placing temperature and heat dissipation. problems. During early stage, design has been made to reserve heat dispersion shaft within the dam proper. Such a scheme, after being carefully studied and compared, it has been revised to adopt the method of adding cooling water and mixing acicular ice as well as burying cooling water pipes within the dam proper, thereby conducting new technique of I-phase and II-phase cooling. It has yielded promising and successful results.
During the high peak period of construction for the Liuxihe Hydropower Station, the total labor force reached 14,000 persons. There are nearly 5 million labor-day to complete the said hydropower station. All items of temporary structures are nearly 100,000 m3. During peak period, the monthly power consumption for construction reached 1.30 million kW.h.
3. Fast in construction speed
The general progress of construction for Liuxihe Hydropower Station is: the planning work of Liuxihe River Basin was started on September1955. The preliminary design was completed on June 1956, altogether lasting 9 months. The project was formally started constructing on August 1956 and the first power set was put into operation on August 1958, the construction of which lasted 2 years. The station was wholly completed on January 1959, the total construction period was less than 2 years. As a whole, the Liuxihe Hydropower Station, starting from the commencement of river basin planning up to fully completion, altogether lasted less than three and half years. The construction speed is comparatively fast.
4. Low in engineering cost
On the aspect of dam site selection, the Liuxihe Hydropower Station has screened five dam sites. In accordance with the concrete topography, geological condition, interfaced with the comparison of various dam types, finally the fourth dam site was selected, where dam site rocks are relatively sound, with thinner layer of weathering and lower in investment. In dam type selection, five alternative schemes have been compared, in which the arch dam is the most preferable for its least investment, being equivalent to 2/3 that of gravity dam or rock-fill dam. In the aspect of engineering quantity, the amount of excavation and residue cleaning as well as the concrete of the dam proper is relatively less in amount. In the design of arch dam, the dam crest spillway scheme has been adopted, which is simpler in layout and economical in engineering cost as compared with river bank spillway and water release outlet within dam proper. Based on the geological condition, a length of 800 m of the power tunnel could merely use shotcrete in stead of concrete lining, thereby reducing the engineering quantity and saving investment. In the layout of power house, the main power house is arranged in line with the subsidiary power house and the central control room is situated on one terminal of the main power house, thus forming a compact arrangement and consequently reducing the engineering quantity. Owing to the fact that optimization has been carried out in the design and the optimal scheme has been selected and the new structure and new technology have been adopted, thus making the investment of cost estimate per unit kW reduced to 1100 yuan (rmb).
The cost saving measures were employed during construction, such as: in the aspect of technologies, as regard to the livelihood during construction, the bamboo structures were adopted for office building and the bamboo reinforced concrete structures were used for the partition wall of warehouse for materials. The upstream cofferdam designed is of rock-fill bodies overflow type. In order to save cement, the coarse aggregates with the max. grain size of 150 mm were adopted in dam concrete. Furthermore, 5 % - 10 % of white soil or 1 % platicizer, 7 % buried stone block were used as additives or coarse aggregate. To utilize later age strength after 120-day as design criteria and to use different grade concrete at different places, etc. are all effective measures to save cement. In the aspect of management, to implement budget of construction drawings, engineering task list, limited amount material list, etc. to reinforce cost management in an overall point of view, to pay serious attention to cost analysis, to combat waste and to establish award for reasonable suggestions, award for saving in engineering issues.
As grave attention has been paid on the saving measures both in technology and management during construction, the actual engineering cost is 40.54 million yuan, being reduced 13.7 % of the total cost estimated., the cost per unit kW being 965 yuan (rmb). The cost was relatively low for a median-sized hydropower station during that time. After 40 years operation, it has witnessed that the saving measures taken in construction did not influence the engineering quality, which was esteemed to be good and promising.
5.Excellent in quality
The attention has been strongly focused on the engineering quality by the construction unit of the Liuxihe Hydropower Station. Various measures have been taken, to observe strictly the quality control procedure. In order to well construct the arch dam, a strict and reasonable organizational design of construction has been made. More strict requirement has been proposed for the excavation treatment for the dam foundation, the in-situ inspection and acceptance as well as the quality control of concrete. With an aim at controlling the precise dimensions of the dam block of a double-curvature arch dam in concrete placement, specific persons have been appointed by the engineering bureau to compute every layer and every block in advance. In order to guarantee the quality of construction, the experiment personnel have been specifically trained. Experiment laboratory has been established. With an aim at controlling the temperature of concrete, the pre-cooling of concrete and cooling water pipes have been buried within the dam. Simultaneously, systems of quality monitoring and accident treatment, etc. have been established together with strict implementation.
All measures implemented during construction have ensured the quality of construction for the project. No crack has been found in the dam proper. The quality of grouting for transverse joints is excellent. The deformation of arch dam is quite small after reservoir impounding. No leakage in the concrete dam proper has been found. The vibration of dam proper during flood discharging is slight. The power tunnel after being put into operation, despite a part of the tunnel has not been lined with concrete, however, the surrounding rocks remain stable.
The Liuxihe Hydropower Station has been put into operation for more than 40 years. However, up to the present moment, all items of the main structures have had smooth functioning, enjoying good praise from various aspects.
6.Briefing on the operation situation of the arch dam
Owing to the fact that the Liuxihe Hydropower Station is reasonable in design and strict in construction, therefore, the quality of the project is excellent. During the past 40 odd years, the project is in smooth operation and normal management. The first periodic inspection on dam safety was carried out in 1989. The appraisal made by the specialist panel witnessed the fact the Liuxihe arch dam has been esteemed as C-class (normal) dam. In 1997, the project has been registered by the dam safety supervisory center as an A-class dam. The second periodic inspection on dam safety has been started from 1999 and will be completed in the first half year of 2000.
The present items and apparatus for safety monitoring in Liuxihe Hydropower Station are: 1. horizontal displacement, new and old video level line system, arch crown inverted plumbing line, dam shoulder inverted plumbing line, geodetic quadrangle plan control net; 2. vertical displacement; 3. variation of structural joints;crack observation on downstream dam surface.
The displacement on Liuxihe arch dam has regular variation on one side, and the non-reversible displacement toward upstream is in existence, which tends to be essentially stable at present. After being operated for 40 odd years, the concrete of arch dam proper has had nice outer appearance. Generally speaking, the overall situation is relatively good. The weathering and erosion phenomena on both upstream and downstream concrete dam surfaces are not serious. Only an extremely small part has naked its coarse aggregates, while most part of the concrete surface are smooth and flush. However, cracks were found on the dam surface during the early stage and operation period, among which the cracks occurred on the downstream surface were more numerous. Practically, no leakage was found either on dam proper or on dam foundation. Besides, the property of cracks is pending further investigation to be clarified. The remaining situations could witness that the structural behavior of the dam is excellent and promising.
7. Precious experience
The completion of Liuxihe Hydropower Station is an important starting point.It is not only served as a creative work for the development of electric power industry in Guangdong Province, it has also accumulated precious experience of hydropower construction. Furthermore, it has trained a lot of personnel and technical mainstay as well. Since 40 odd years?operation and commissioning of the station, it has provided low-price power for industrial and agricultural production of the Guangdong Province. It has played evident role for flood control, irrigation and domestic use for the local people. The Liuxihe Hydropower Station is the first hydropower station in Guangdong Province since the founding of New China. It has shouldered the responsibility of training task, training the operation personnel at various levels for other provinces and districts and providing a good base for practice, as well as playing an important role for the development of hydropower undertakings.

Sardar Sarovar dam (File Photo)
AHMEDABAD: Though the monsoon has just arrived in Gujarat, the water level of the Sardar Sarovar Dam over Narmada river is rising fast and has reached 127.46 metres, just 11 metres short of its maximum capacity, officials said on Thursday.
With the fresh inflow of upstream water, mainly from the Omkareshwar and Indira Sagar dams located in Madhya Pradesh, the live water storage of the dam has reached up to 2,700 million cubic metres, they said.
"The water level of the reservoir has reached 127.46 metres," Sardar Sarovar Narmada Nigam Limited director P C Vyas said.
This is just just 11.22 metres short of its full reservoir level of 138.68 metres.
In September last year, the water level of the dam, located at Kevadiya in Gujarat's Narmada district, reached its highest capacity at 138.68 metres for the first time since its height was raised in 2017.
Vyas said with an inflow of around 40,000 cusecs, both the river-bed and the canal-head power houses on the dam have been started from Wednesday.
While five river-bed power houses are generating 1,000 MW electricity, two canal-head power houses are generating 100 MW at present, he said.
As a result, 7,000 cusecs of water is being discharged into the Narmada main canal, while 33,000 cusecs is going into the Narmada river downstream.
"At present, both the river-bed and canal-head power houses are generating around 17 to 20 million units of electricity worth Rs 3.5 crore to Rs 4 crore every day," Vyas said.
Simultaneously, the water discharged into the main canal is being utilised to fill up dry lakes and for drinking and agriculture purposes through canal network, he added.

In a letter released to media on Saturday, Patnaik also urged Soren to ensure storage of water up to full reservoir level (FRL) in Chandil Dam in the monsoon season for mitigation of flood in Odisha.
The Chief Minister said Subarnarekha irrigation project of Odisha will be able to utilise its full irrigation potential only after completion of Ichha dam by the Jharkhand government.
I am happy to know that the government of Jharkhand has taken up Ichha dam construction work recently. Odisha government will extend all cooperation for Ichha dam construction and reimburse Odishas share of the cost of the dam in time, said Patnaik.
He said a sum of Rs 1,026.91 crore has been paid to Government of Jharkhand for the above works till date against the estimated share cost of Odisha of Rs 1,208 crore (2016 Price level).
I am told that 36 villages of Odisha are affected under Ichha Dam reservoir sub-mergence area at FRL 225m. Accordingly, land acquisition and R&R work in Odisha portion have been taken up, said Patnaik.
Patnaik further pointed out that while Chandil Dam across river Subarnarekha has been completed since long but water has been stored up to reservoir level (RL) 181.50 m during monsoon against full reservoir level (FRL) of 192 m due to resettlement and rehabilitation (R&R) issues.
As full storage capacity has not been utilised in the dam during monsoon season, Odisha is facing flood havoc more often, he added.
