An accurate length of separation and reattachment zones are achieved. A finite-volume method (FVM) has been developed to study incompressible flow in a forward-facing step along with artificial compressibility technique. The governing equations are solved by time marching using a fifth-order Runge-Kutta time stepping. The proposed explicit finite volume method uses a new biasing discretization in space. The proposed model reveals that pressure and velocity fields are determinable in a wide range of Reynolds numbers up to 330 without artificial dissipation. The numerical results agree well with the available experimental and numerical data. %U https://jmee.isme.ir/article_20571_88bc265f6b1e9151f88de78c466b52a9.pdf
