| Abstract: | The RNGk-ε double equation turbulent model is adopted in this paper to process the numerical simulation and to analyze the influence of step-down depth on hydraulic characteristic of energy dissipater with step-down floor. The test results are then compared with the numerical simulation results to verify the feasibility of mathematical model. It is a valuable source of reference to the step-down hydraulic jump dissipater design. |
