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,為探求水輪機內(nèi)部的流動規(guī)律,優(yōu)化水輪機設計,為水輪機的安全穩(wěn)定性運行和機組的故障診斷提供幫助。對導葉內(nèi)部的流動進行流場計算和流固耦合振動特性的動力計算就顯得十分必要。
