| Abstract: | The mathematic relationship of the temperature field solved by the fluid and solid coupling is clarified according to hydromechanics and heat transfer theory.The solution domain including 1/8 region of generator along circumferential direction was established based on the electromagnetic structure,ventilation and cooling method of 1.5 MW doubly-fed wind generator when combined with fluid flow and heat transfer characteristics inside the motor.Fluid and temperature field inner generator were calculated numerically by using finite volume method,and the solving results was analyzed in detail.Besides,the velocity and flow distribution of cooling air in the circulation area were obtained.Then the temperature distribution and heat transfer characters of the electrical motor were analyzed.Finally,the calculated results show good agreement with the measured results,which will provide a theoretical basis for the operation of wind generator and the design of greater capacity of wind generator. |
