| Abstract: | Heat transfer and operating performance of generator are closely related to the ventilation structure and fluid flow behaviour.Taken a 3MW large doubly-fed wind generator as an example,physical model of three dimensional fluid and temperature coupled field was established according to hydromechanics and heat transfer theory.On the base of the correctness of researching method and computing result proved by the temperature rise distribution of the whole generator,the space distribution characters of differen... |
