Methodology of Cavitation Modelling in Diffusers
Original language description
Cavitation is undesirable phenomenon occurring mainly in the flow of water in pumps and turbines, and therefore it is necessary to pay attention to it. The purpose is to explore the possibility of the mathematical modelling of the cavitation using Singhal cavitation model, which solves the multiphase flow of water and vapour. The issue can be solved taking into account the non-condensable gas (air). Singhal cavitation model was selected on the basis of good experience in the modelling of dynamic cavitation changes in the Laval nozzle [2], [10]. This article presents two alternatives. The first variant is testing a mathematical model for flow in a simple geometry of the cone. The second variant resolves the formation of cavitation rope behind vortex generator and the results are compared with experiment.
