Abstract

In this paper,the Reynolds Euqations are closed with standard k-e model.A method called Geo-reconstruct is used to track the free surface and the PISO algorithm is used to calculate the flow field.The velocity field of the interior of water jump behind a sluice is put to verify the mathematical model.The comparison between the calculated results and the measured results shows that this mathematical model is greatly possible and practical.
