| Abstract | 利用LANS-α(Lagrangian-averaged Navier-Stokes-alpha)模型对传统的光滑粒子法进行改进.通过模拟半浮力和零浮力水平圆柱的入水过程,验证改进的光滑粒子法.模拟结果与实验以及其它数值模拟结果符合的很好,表明改进的光滑粒子法适用于研究物体入水问题. |
| Other Abstract | A modified Smoothed Particle Hydrodynamics(SPH) in Lagrangian-averaged Navier-Stokes-alpha(LANS-α) model was developed to simulate water entry flow.Water entry of a half buoyant cylinder and a neutrally buoyant cylinder were simulated.SPH results are in good agreement with reported experiments and numerical results of others.It shows that the modified SPH method is practicable in simulation of water entry flow. |
