Abstract：A. numerical model for 3-D turbulent flow in the sump of the pump station is presented. A reasonable boundary condition for the flow in the sump with double water intakes, each of which may has different flow rate respectively is proposed. The finite volume method is employed to solve the governing equation using the body fitted grid generated by multiblock grid technique. Using the method obtained in this paper, the fluid flow in the sump of the pump stations with two water intakes is calculated. The numerical result of the examples is fairly good.
