| 中文摘要: |
| 本文提出了混流式水轮机转轮内三元空化流场的数值分析方法和一种新的空穴模型，实现了水轮机转轮内三元空化流场和叶片上三元空化区域的预测.通过比较岩滩水电站模型转轮的空化试验结果及其三元空化流场的数值分析结果，可以证明：基于此种准三元空化流动理论的转轮内空化流场分析结果具有定量上的准确性，具有工程实用价值。 |
| 英文摘要: |
| The numerical simulation and a new cavity model for the 3-D cavity flow field in the runner of a mixed-flow turbine are presented in this paper. The comparison of the turbine model cavitation test with the numerical analysis for the model runner of the Yantan hydraulic power station, show that the numerical methed is accurate and can be used in practice. |
