摘要 跌坎型底流消能工是在常规底流消能工基础上发展起来的一种新型消能工。就入池角度对跌坎型底流消能工水力特性的影响进行数值模拟,并将模拟结果与试验数据对比分析,二者基本吻合,表明数值模拟方法有效可行。同时,研究发现入池角度对跌坎型底流消能工水力特性影响较大,选择合适的入池角度以提高消能效率是确定该型消能工体形的关键之一。 The energy dissipater with step- down floor is a new type of the conventional lip energy dissipater developed on the basis of the conventional energy dissipaters of hydraulic jump. The paper adopts numerical simulation to analyze the influence of intake angle on hydraulic characteristic of the energy dissipater with step - down floor. And the results of numerical simulation tally with the data obtained from hydraulic model tests on the whole after comparison and analysis. It indicates that the numerical simulation method is effective and feasible. In addition, the research finds that the intake angle has significant influence on the hydraulic characteristic of energy dissipater with step - down floor and that selection of an appropriate intake angle to improve the efficiency of energy dissipation is one of the key elements of designing the lip energy dissipater of hydraulic jump.
