Abstract

Smoothed particle hydrodynamics (SPH) is tested for simulating flow driven by high speed underwater body (FDUB). Developing history of supercavity induced by a body is predicated by SPH. Shape of developed supercavity derived by SPH is compared with result given by principle of independence of cavity sections expansion of Logvinovich. Ghost particle method and Dummy particle method, that remedy boundary deficiency of SPH, are combined to implement wall conditions.
