| Abstract: | D isoparametric element method that is used to solve stator temperature field of large synchronous generator is presented.Based on analysis to the hybrid relationship among wall temperature of radial ventilating groove,stator surface coefficient of heat transfer and air speed in ventilating groove,the hybrid field of fluid body and structural parts is solved using numerical method.Finally,Finite Element Method is used to simulate inlet air speed,which affects the calculation results of stator temperature,and some useful conclusions are presented. |
