摘要
为了研究喷嘴特性对冲击式水轮机性能的影响,在试验的基础上,采用CFD技术对喷嘴自由射流进行多相流的数值模拟。研究结果表明:在相同工况下,不同形状的喷嘴所产生的射流能量特性有明显差异。
To investigate the influence of nozzle characteristic on Pelton turbine, the free jet flow of the nozzle was numerically simulated by CFD technique for multiphase flow on the base of experiment in this paper. The results of research indicate: jets discharged out of nozzles with different shape configuration display different energy performance obviously in the same operating condition. This is also the elementary research on the internal flow of Pelton turbine with the newest numerical simulation method in our country.
