Numerical Simulation of Rotor Temperature Field for Large Wind Power Generator

In this paper,take a 1.5MW doubly-fed wind power generator as an example,the fluid flow and heat transfer within the rotor of the power generator are studied.According to the generator ventilation structure and heat transfer characteristics,three-dimensional solution model of the rotor in 1/8 region is established,and the solving domain is coupled solving by CFD technology.Thus,the fluid flow and temperature distribution characteristics inside generator rotor are obtained.
