Abstract: Through study on Goupitang Project on the Wujiang River, the velocity field and the pressure field of impinging jets in the water cushion pool have been numerically simulated using 2D large eddy method, and the simulation results have been compared with experimental data.It is found that the calculated data are in primary agreement with the test values.
