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(jī)內(nèi)部的流動(dòng)規(guī)律,優(yōu)化水輪機(jī)設(shè)計(jì),為水輪機(jī)的安全穩(wěn)定性運(yùn)行和機(jī)組的故障診斷提供幫助。對(duì)導(dǎo)葉內(nèi)部的流動(dòng)進(jìn)行流場(chǎng)計(jì)算和流固耦合振動(dòng)特性的動(dòng)力計(jì)算就顯得十分必要。
