基于FD/MLSFD的混合算法计算二维浅水方程
FDM/MLSFD hybrid algorithm based calculation on 2-D shallow water equations
摘要
Abstract
Based on the combination between the mesh-free least square-based finite difference(MLSFD)method and the conventional finite difference method ( FDM) , a hybrid algorithm is created herein, and then the problems from the coupling of both the different algorithms for the hybrid algorithm concerned are studied and solved. Furthermore, the hybrid algorithm is applied to the calculation of the 2- D shallow water equations. Through the numerical simulation of the flow around circular cylinder with a high Reynolds number( Re = 10 ) , the hybrid algorithm is demonstrated to have a high accuracy for the numerical simulation made on the 2- D shallow water equations.关键词
