Numerical simulation of flow field in diversion channel of large pumping station

The 2_D average water depth mathematical model in orthogonal curvilinear coordinate system is used for the numerical simulation of the flow field in the diversion channel of large pumping station. The orthogonal gird is generated by Poisson equation; the channel bottom elevation data of the gird points are given by quadrilateral interpolation method; and the equations are solved by SIMPLEC method. The simulated velocity field and the average vertical velocity of Jinkou pumping station diversion channel are in fair agreement with the measured results in model test.
