Pressure surges-experimental investigations and calculations with software codes using different physical models and assumptions

摘要

Within this paper an overview about six recently performed experimental pressure surge scenarios is given. Two scenarios are discussed inmore detail. There models of different physical depth are used to calculate cavitaion hammer (first and second model) and the maximum length of the vapour bubble downstream a closing valve (third model), respectively. For the calculation of cavitation hammer two models are used, the full concentrate vapour cavity model (7) and a three phase model (5).
