A numerical simulation program to analyze incompressible flow has been developed. The artificial compressibility method of primitive variable formulation, which has been developed for compressible flow, was used in this work. Specifically, the governing Navier-Stokes equations were solved with weighted essentially non-oscillatory (WENO) scheme. In addition, the Lower-Upper Symmetric-Gauss-Seidel (LU-SGS) method was adopted to enhance numerical stability and to achieve fast convergence. Two classical incompressible flow, cavity flow and backward —step flow, where examined to validate the numerical simulation program. Good agreement between the numerical simulation results and the published experimental data in the literature was obtained.
