摘要

结合乌江构皮滩水利枢纽工程，以二维大涡模拟方法研究水垫塘内的冲击射流流速场及压力场，并与试验研究成果进行比较分析，结果发现计算值与试验值基本吻合。

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.
