Abstract: In this paper, a numerical solution of two-dimensional laminar flow over a backward-facing step at low Reynolds numbers is presented. Convective flux modeling in a tinite volume method is used to solve the incompressible Navier-Stok equation in conjunction with artificial compressibility. A fifth-order Runge Kutta's scheme has been used for marching in time. The viscous was discredited by a second-order technique. Using the improved flux model led to an improvement in the convergence rate. The numerical results are compared with the available experimental and numerical data, where there would be a favorable agreement between them.
