Краткое описание

A pressure-based algorithm is developed and applied to compute turbulent cavitating flows. To represent the cavitation dynamics the two models employed a mass fraction equation with pressure dependent source terms are used. The test problems include flows over axisymmetric cylindrical bodies and a planar hydrofoil at different cavitation and Reynolds numbers. The results show satisfactory agreement with experimental data in pressure distribution. To demonstrate the capabilities of the method, the results of steady-state three-dimensional simulation of cavitating turbulent flow over the water turbine blades are presented.
