Numerical Simulation of Optimized Forebay of Pumping Station

The incompressible N-S equations are solved by the finite volume method. Based on the standard k-e model, the SIMPLEC algorithm is applied for the solution of the discretization governing equation. Using CFD, the flow pattern in the forebay of pumping station is revealed. The calculation results showed that there were large scale recirculation in the forebay of original scheme and the flow patterns of optimized forebay with bottom sills were improved. The calculated results were in good agreement with experiment data, which show that the calculated model was reliable and practical.
