随着计算机流体动力学(CFD)预计冲击式水轮机自由面流能力的稳步提高,介绍了最近的发展情况,展示了该领域的最新技术水平。在初步讨论了详细的确认结果后,讨论了某些典型的应用,如性能预测和多喷嘴效应。对于所谓流体结构相互作用(FSI)分析,也介绍了冲击式水轮机水斗的耦合流体和结构模拟。还讨论了考虑实际入流模式对转轮研制的重要性。 As CFD predicts a steady increase in the free surface flow capacity of an impulse turbine, recent developments have been introduced demonstrating the state of the art in this area. After a preliminary discussion of the detailed validation results, some typical applications were discussed, such as performance prediction and multi-nozzle effects. For the so-called Fluid Structure Interaction (FSI) analysis, the coupled fluid and structure simulation of the impingement water turbine bucket is also introduced. Also discussed the importance of considering the actual inflow mode on the wheel development.
