| 中文摘要 | 采用全三维反问题设计方法,按照水泵工况确定设计参数,从水轮机方向进行流场计算,完成某一中高水头水泵水轮机转轮的水力设计。针对设计开发的转轮,通过模型实验测试其在不同运行工况下的性能。结果表明,设计的水泵水轮机转轮在水泵工况下的最高机组效率达到91.34%,且机组运行平稳;水轮机工况的最高机组效率为88.5%。基于全流道粘性数值计算的转轮内部流动分析表明,水泵工况下,水流光顺地通过流道,转轮内部流动损失较小;水轮机工况下,转轮进口附近存在较严重冲击损失且叶片背面低压区面积较大,影响转轮的作功能力。; 3D inverse design method was applied to configure the runner geometry of a middle-high head pump-turbine, in which design parameters were given according to pump operation and iterative calculations conducted from turbine direction. Model tests were performed to measure performances of developed runner under different operating modes and points. Test results show that the highest efficiency under pump mode is 91. 34%,and highest efficiency under turbine mode is 88. 5%. Internal flow analyses based on viscous full passage computations show that water pass through the passage smoothly with smaller loss under pump mode,while rather serious incidence loss exists at runner inlet and large low pressure area exists at suction side under turbine mode. |
