The integral equations governing the three - dimensional viscous flow inside the turbo - machinery in the rotating coordinate system are presented in this paper , the viscous effects are simulated by the distributed body force described by professor denton j . d . the time - marching method and explicit finite volume difference scheme are employed to solve the flow inside the turbo - machinery 本文給出了相對(duì)旋轉(zhuǎn)坐標(biāo)系下葉輪機(jī)械內(nèi)部三維粘性流動(dòng)的守恒型積分型方程組,利用dentonj . d .教授的粘性體積力法來(lái)模擬粘性對(duì)葉輪機(jī)械內(nèi)部流動(dòng)的影響,采用時(shí)間推進(jìn)法和有限體積差分格式對(duì)葉輪機(jī)械內(nèi)部的流動(dòng)進(jìn)行求解。
