The volume of fluid(VOF)method is applied to track the free water surface,and the RNGk-εturbulent model is used to close the two-phase flow time-averaged equations.The hydraulic characteristics of free hydraulic jumps on triangular corrugated beds of a stilling basin under 6kinds of conditions are studied by numerical simulation.The finite volume method is used to discretize the differential equations;and the coupling velocity and pressure equations are solved with the pressure-implicit method of splitting operators(PISO)algorithm.The research results show:near the corrugated beds surface generates vortexes rotating clockwise,whose dimensions gradually reduce along the flow direction.The variation of the maximum velocities on cross-sections along the flow direction under different conditions are similar.The maximum values and the maximum gradients of turbulent kinetic energy and dissipation rate occur near the gate;and with an increase of the inlet cross-sectional Froude number,the maximum values of turbulent kinetic energy and dissipation rate increases.The theoretical and actual energy dissipation rates increase with an increase of the inlet cross-sectional Froude number.
