The water hammer phenomenon, which occurs as a result of changes in the boundary conditions of hydraulic systems, can cause major and dangerous problems. Opening or closing of the valve component, sudden power loss or pump startup, change of water level in the reservoir, etc. can be examples of these boundary condition changes. These problems must be considered at the design stage of hydraulic pipeline systems in order to predict and prevent dangerous results. Since the calculation of water hammer analysis manually is very long and tiring, various software has been developed throughout the world. Within the scope of this study, a computer program has been developed to analyze the time-varying flows in hydraulic systems and to produce solutions to possible problems with the help of simulation. The program, which is coded in the C Sharp programming language, is created in the Visual Studio platform. The primary purpose of the program is to find fast and practical solutions to reduce the negative impact of water hammer phenomena that may occur in hydraulic systems. In this program, the characteristics method is used to solve the equations of time-varying flow. The accuracy and reliability of the program are provided since the results of the sample studies tested on the program are similar to the results in the literature. It is hoped that this program, which is ready to use, would be improved by becoming more comprehensive with new boundary conditions and additions in the future.

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 effective surge tank dimensions in hydropower plants under various hydraulic conditions Berberoğlu, Pınar; Bozkuş, Zafer; Department of Civil Engineering (2013) In water conveyance systems, sudden changes in the flow velocity cause a phenomenon called waterhammer associated with high pressure head changes. Unless a control device is used as a precaution, waterhammer may result in costly damages and even in some cases, loss of human lives. In light of this concept, different control devices that can protect the systems against waterhammer are introduced so that the great pressure differences are absorbed and the system is maintained undamaged. In this thesis, the ma...
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...
A Study on Tensile Strength of Compacted Fine-Grained Soils Dagar, Volkan; Çokça, Erdal (Springer Science and Business Media LLC, 2020-08-01) The tensile strength of clay is a major mechanical parameter and the main controlling parameter of tensile crack development which is generally encountered in geostructures. In this experimental study, 8-shaped direct tensile test and split tensile test were used to measure the tensile strength of compacted clay soil. Unconfined compression tests on the same clay samples were also carried out. Tensile strength and unconfined compression test results were compared. Laboratory tests were performed on Ankara c...
