摘要
A parallel numerical method is employed to solve the two dimensional Navier Stokes equations in primitive variables for incompressible flow.The computing process contains two sections.The first section uses the GE (group explicit) method with high parallelism to solve the velocity equations.The second section solves the pressure equation by a successive underrelaxtion iteration method in red black order.Results are given using these methods on a parallel computer.Until recently,GE method has rarely been used to solve the Navier Stokes equations.
