Abstract

The discrete time Navier-Stokes equation (22) by the semi-implicit lime evolution scheme gives an approximate solution to the incompressible Navier-Stokes equation (4). But the pressure P* and the posidon U* in die equation (22) do not satisfy die incompressibility (2), Thus die computed pressure P* oscillates numerically. The discrete lime Navier-Slokes equation (22) must be modified in order to converge to die Navier-Stokes equation (4).

不可压缩流体动力学CG动画的粒子法数值振荡问题
离散时间Navier-Stokes方程(22)采用半隐式灰演化格式给出了不可压缩Navier-Stokes方程(4)的近似解,但模具方程(22)中的压力P*和位置U*不满足模具不可压缩性(2),因此模具计算压力P*在数值上振荡。为了收敛于离散的Navier-Stokes方程(4),必须对离散的Navier-Slokes方程(22)进行修正。
