Multiphase flow analysis of cylinder using a new cavitation model

Abstract

Cavitating flow simulation is of practical importance for many engineering systems, such as marine propellers, pump impellers, nozzles, injectors, torpedoes, etc. The present work is to test a new cavitation model. The governing equation is the Navier-Stokes equation based on an homogeneous mixture model. The solver employs an implicit preconditioning algorithm in curvilinear coordinates. The computations have been carried out for the cylinders with 0-, 1/2- and 1-caliber forebody and then compared with experiments and other numerical results. Fairly good agreement with experiments and numerical results has been achieved.
