Abstract The 2-D average water depth mathematical model in orthogonal curve-linear coordinate systemis used for the numerical simulation of the flow pattern in the front inflow forebay of pumping station. Theorthogonal gird is generated by Poisson equation, the pool bottom elevation data of the gird points is given byquadrilateral interpolation method, and the equations is solved by SIMPLEC method. The influence of thechange of divergent angle and the selection of running pumps on the flow pattern in the forbay is analyzed bythe simulated velocity field and the average vertical velocity, the conclusion is selfsame with the designtheory of forbay which based on experiments.
