摘　　要：依据计算流体力学理论,应用有限体积法对大型同步发电机定子通风沟流体速度进行了计算与分析,并且对全流场中,由于转子旋转离心作用转子内流体速度(转子旋转流体场)对定子径向通风沟流体速度的影响进行了仿真计算与分析,得出一些有益的结论。Fluid velocity of stator grooves for a large- capacity synchronous generator was calculated and analyzed using finite volume method according to hydromechanics, and the effect of fluid speed inside rotor due to the centrifugal effect of rotor＇s circumrotating on the fluid velocity of stator radial grooves was calculated and analyzed simulatively, some useful conclusions were obtained.
