【Abstract】 k-εdouble-equation model is used to close Reynold time-averaged equation. vof method is used to track the free face, and piso method to couple the velocity field and pressure field. The outflow in the hole of sluice gate is calculated by numerical simulation. The calculated results are identical with the experiment, indicating this method is feasible.更多还原
