摘要
三次伪质点 (CIP)方法是有效求解广义双曲型偏微分方程的一种数值方法 ,将这种方法进行推广 ,应用到不可压Navier -Stokes(NS)方程的求解中 ,并以驱动方腔流作为算例 ,验证了此方法的可行性 .CIP方法作为一种显式格式求解不可压NS方程 ,具有计算量小 ,程序易实现等特点 .
The cubic interpolated pseudo-particle method(CIP)has been used to solve the general hyperbolic equations.In this paper the CIP method is extended to solve unsteady incompressible NS equation.Choosing the square cavity fluid as an example,we prove the feasibility of CIP method.As an explicit scheme to solve the unsteady incompressible NS equation,the CIP method is characterized by less computing time and simple computer program.
