| 摘 要： | 以某高海拔水电站混流式机组为研究对象,应用ANSYS软件建立从蜗壳进口到尾水管出口的过流部件全流道模型,划分网格后导入Fluent17.0进行模拟计算。分析结果表明,模拟的流场与理论上的流场规律相符,模拟结果有较高可靠性。该方法可作为水轮机优化设计的辅助手段,预估水轮机的性能和流场特性。

| Abstract: | Taking a mixed-flow unit of a high-altitude hydropower station as the research object,a full-flow channel model of the overflow components from volute inlet to draft tube outlet is established by using ANSYS software,and then the grid is divided and introduced into Fluent17.0 for simulation calculation.The analysis results show that the simulated flow field agrees with the theoretical flow field law and the simulated results are reliable.This method can be used as an auxiliary means for turbine optimization design to predict the performance and flow field characteristics of the turbine. |
