摘要
提出了一种用改进的强隐式方法求解三维不可压缩粘性流动的交错网格有限体积法．该方法在ＳＩＭＰＥＲ算法的基础上，对Ｎ－Ｓ方程的对流项采用ＱＵＩＣＫ格式离散，利用ＭＳＩ方法求解代数方程．数值计算表明本方法具有计算稳定、收敛速度快等特点．
A new staggered finite volume method on three-dimensional incompressible viscous flow by using MSI procedure is suggested in paper.Based on SIMPLE-revised (SIMPLER)algorithm,this method uses QUICK scheme to discrtet the convective term of Navier-Stokes equation,and MSI(Modified Strongly Implicit)procedure to solvealgebra equation.It is demonstrated that this method improves the convergence and saves computational cost.
