Water hammer is an undesirable event, caused by sudden flow changes in confined pipe systems. When it occurs, its consequences can be very costly and even sometimes deadly. In general, it may be encountered in the penstocks of hydropower plants, water transmission lines, water networks, etc. Therefore, the operation guidelines of the hydropower plants should be defined correctly and if necessary, preventive measures should be considered. In the present study, water hammer problems in pumped-storage hydropower plants supported by wind energy (water-wind hybrid systems) are investigated. Time dependent flow conditions in the penstocks are studied by the use of the computer software, HAMMER. The software solves nonlinear differential equations by using method of characteristics. Firstly, hydraulic transients for various operational cases are investigated using some scenarios. In this study, only the scenario 5 which gives the most critical results is investigated.

Investigation of Water Hammer Problems in the Penstocks of Pumped-Storage Power Plants Dinçer, Ali Ersin; Bozkuş, Zafer (2014-10-25) Waterhammer is an undesirable event, caused by sudden flow changes in confined pipe systems.

In general, it may be encountered in the penstocks of hydropower plants, water transmission lines, water networks, etc. Therefore, the operation guidelines of the hydropower plants should be defined correctly.

Investigation of waterhammer problems in the penstocks of pumped-storage power plants Dinçer, Ali Ersin; Bozkuş, Zafer; Department of Civil Engineering (2013) Waterhammer is an undesirable event, caused by sudden flow changes in a confined pipe system. When it occurs, its consequences can be very costly and even sometimes deadly. In general, it may be encountered in the penstocks of hydropower plants, water transmission lines, water networks, etc. Therefore, the operation guidelines of the hydropower plants should be defined correctly.

Development of a computer code to analyse fluid transients in pressurized pipe systems Dalgıç, Hasan; Bozkuş, Zafer; Department of Civil Engineering (2017) Sudden change of flow conditions in a pipeline may cause the flow to become time dependent and would start an undesirable physical phenomenon called water hammer. These sudden changes can be caused by variety of scenarios and some of them include valve operations (opening or closing), sudden power loss at pump stations and load rejections or load acceptance at the turbines, etc. Because of its very costly to solve, and sometimes deadly results, it is quite important that transient scenarios be considered fo...
Investigation of water hammer problems and potential solutions in pump discharge lines Erdem, Recep Çağrı; Bozkuş, Zafer; Department of Civil Engineering (2019) Disturbance in boundary conditions of a hydraulic system could cause rapid change in flow velocity in confined pipe systems. Pressure wave leading to an event called water hammer may occur as a consequence of that disturbance. Water hammer could lead to catastrophic failures on the hydraulic systems. Thus, proper protection measures should be defined and installed in the system before it is put into operation. The aim of this study is to analyze a pumped discharge line and ensure its safe operation against ...
Numerical investigation of protection measures against water hammer in the Yeşilvadi hydropower plant Dursun, Samet; Bozkuş, Zafer (null; 2014-10-25) Pressurized hydraulic systems are vulnerable to water hammer, which is an unsteady hydraulic problem. Changes of direction or velocity of the water in the system cause sudden increase in pressure and pipeline may collapse or burst. The purpose of this paper is to analyze pressure relief valves (PRV), which are used as protection measures against water hammer, numerically and compare the results with measured field data of a run-of-river hydropower plant project. The hydropower system is investigated numeric...
