三维溃坝流的光滑粒子动力学方法模拟
Numerical simulation of 3D dam-break flow using smoothed particle hydrodynamics
摘要
Abstract
We present a numerical simulation of 3D dam-break flow with smoothed particle hydrodynamics (SPH).In order to reproduce the phenomena of splashing and coalescence to the life,the turbulence model,i.e.,the mixing length model is implemented in the SPH code.In order to prevent fluid particles from crossing the walls,we propose an improved treatment technique of wall boundary,which is suitable for 3D numerical simulation.3D dam-break flow is numerically simulated by the improved SPH method. In particular,both cases,i.e.,without any obstacle and with a cylindrical obstacle are considered.It is demonstrated that the improved SPH method can nicely capture the variation of the free surface and well describe the dynamic process of dam-break flow with accurate and stable results.关键词
