中文摘要：
考察SPH对水下高速运动物体引起的流动的模拟，并观察空泡发展过程．将SPH计算空泡形状与Logvinovich独立膨胀原理给出的空泡形状进行比较．固体壁面条件的实施通过联合使用两种不同的虚粒子方法（Ghost Particle Method，Dummy Particle Method）实现．
英文摘要：
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.
