| 1. | Hence , they that flow field calculation and dynamical computation of fluid - solid coupling dynamic characteristics are carried out to search flow law in the hydraulic turbine , optimize the design of scroll casing , guide vane , blade and draft tube , and they can apply useful to the monitoring and fault diagnosis system of hydroelectric set as well 因此,为探求水轮机内部的流动规律,优化水轮机设计,为水轮机的安全稳定性运行和机组的故障诊断提供帮助。对导叶内部的流动进行流场计算和流固耦合振动特性的动力计算就显得十分必要。 |
