【Abstract】 A forced hydraulic jump is calculated and simulated by solving the two dimensional imcompressible N-S equation, together with the k-ε model. The free surface shape, pressure, and velocity distribution of the flow are given after each time step. The computational result and the experimental result are in good agreement. The code GRAFST can be used to calculate general two dimensional transient turbulent flows with free surfaces.更多还原
