Abstract：To study the heat dissipation performance inside the nacelle structure of the megawatt grade wind turbine,three different air distribution s of bottom to side,side to tail and side to side are proposed on the basis of typical structure of bottom to tail.The CFD software is used to analyze the temperature field of the four different air distributions inside the nacelle,and the results of the numerical simulation are compared.In the course of studying,a new method of evaluating the air distributions uniformity based on the heat source perturbation is proposed,and the problem of evaluating the air distributions uniformity without reference has been solved.The results show that the bottom to top method whose temperature field is proven to be the best in all forms.
