非对称溢洪道进口的优化研究

Optimization study on asymmetric inlet of spillway

溢洪道是水库枢纽工程中主要的泄水建筑物,其型式及布设方式直接影响着工程安全。为了削弱进口非对称来流对溢洪道的不利影响,本文采用CLSVOF与RNG方法进行数值计算,针对非对称来流下的溢洪道进行多种布置方案的水力特性研究,经优化和分析对比,给出了经济合理的布置型式。并通过模型试验对数值计算结果进行准确性验证。

The spillway is the main sluice structure of the reservoir project and its type and layout mode have the direct impact on the safety of the engineering. In order to reduce the unfavorable influence of asymmetric inflow on the inlet of the spillway, the paper carries out the numerical calculation based on the CLSVOF and RNG k~ε methods, studies the hydraulic characteristics with multiple layout schemes according to the spillway under asymmetric inflow. Through the optimization and comparative analysis, the economic and reasonable layout mode is put forward. The accuracy of the numerical calculation results is verified by model test.
