Abstract

An evaluation of inhomogeneous model for computations of unsteady cavitating flows is presented. The unsteady cavitating flows around the hydrofoil is simulated with the homogeneous and inhomogeneous model, respectively, and the numerical results are compared with the experiment. The results show that due to the consideration of the interaction between the phase, the inhomogeneous model simulates the details of transient flows more accurately, a re-entrant flow and sharp interface are observed. Meanwhile it can better predict the periodic shedding of large-scale bubbles and the hydrodynamic unsteady characteristics.
