In view of the non-homogeneous environment of the fighter cockpit, the PMV-PPD method for the human thermal comfort evaluation, which is commonly used in engineering and based on the lumped parameter method, has significant limitations. In this paper, a thermal comfort evaluation method based on Fiala human physiology model and Berkeley thermal comfort model is discussed. The thermal comfort and the air distribution in a fighter cockpit are studied and analyzed by using Fluent and TAITherm software. The distribution of thermal sensation, thermal comfort, skin temperature of human body are simulated, and the influences of mean environmental radiation temperature and the solar radiation on human comfort are compared and analyzed. The research method and results have great contribution to the optimization design of the air distribution in the fighter cockpit.
