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 ...
