FLUENT software. The paper simulated the air organization of transformer room by right mathematical model and 空 w physical model, verified the right of the design parameter, then simulated various ventilation methods, found out the best 通w method and the influence of difference inlet velocity. The result has stronger guidance to practical application and 暖w supports the ventilation design of transformer room. / / Keywords: transformer room, cooling and ventilation, numerical simulation, ventilation method
