摘要
采用Girimaji非线性紊流模型和Willam-Warnke五参数破坏模型分别模拟弯肘形尾水管水流状态和混凝土材料,并使用APDL语言编制了尾水管隔墩的结构和水力联合优化程序。使用该程序对一河床式水电站尾水管技术改造进行分析,得到了隔墩下移的较优值,为工程设计提供了可靠的数值依据。
Based on Girimaji non-linear turbulence model and William-Wamke 5-parameter failure model, both the flow regime and concrete material of the elbow draft tube are simulated, and then a combined structural and hydraulic optimization program for the dividing pier of elbow draft tube is compiled with ANSYS Parametric Design Language（APDL）. When the program is applied to the calculation for the technical improvement on the draft tube of a hydropower station in river channel, not only a better value for the move-down of the pier is obtained, but also a reliable data basis is made for the engineering design of the project.
