Based on the basic principle of smoothed particle hydrodynamics(SPH) method,the paper gave 2-D SPH Fortran program to make numerical simulations for Poiseuille flow and Couette flow which are Laminar Flow between two parallel flat plates after a comprehensive consideration of several kinds of settings on solution conditions.Compared SPH with theoretical analysis solution and simulation results which use Flow-3D numerical simulation software,this paper discovers that they are very anastomosis.The results rea...
