Abstract: The classical theory of liquid transient flow in pipelines (waterhammer) usually draws on the following basic assumptions, 1234:

Abstract: The paper presents the results of investigations carried out in connection with a penstock rupture at a small hydropower plant in Poland. The investigations comprised material tests of the ruptured penstock shell, analysis ...

Abstract: The paper presents a comparative analysis of calculations performed basing on the selected unsteady friction models and their validation based on the results of own experimental tests. The ...

Abstract: This paper presents a new method for calculating pressure fluctuations in pipelines during a water hammer with liquid column separation. The method is based on the discrete-vapor-cavity model ...

Abstract: The authors previously described a new method [based on the new discrete vapor cavity model (new DVCM)] for numerical prediction of pressure changes during the water hammer with liquid column separation together with results ...

Abstract: The paper presents the results of calculations of the water-hammer course accompanied by the column separation caused by a rapid closure of the inline valve. The most important problem which the paper is dealing with is ...

Abstract: One of the basic flow rate measurement methods applied in hydropower plants and recommended by the International Standard IEC 60041–1999 and American National Standard ASME PTC 18–2002 is the ...
