摘要
采用RNGk-ε双方程紊流模型进行数值模拟,就跌坎深度对跌坎型底流消能工水力特性的影响进行分析,并将模拟结果与模型试验观测值进行了对比,验证数学模型的可行性,为跌坎型底流消能工的设计提供参考.
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.
