摘要：
A wall heat transfer boundary condition model and an air supply boundary condition model of the air distribution system of a fighter plane cockpit are established according to its features of air flow and heat transfer. Based on these two models, an air velocity and temperature numerical simulation flat of the cockpit is established and an experiment is carried out to prove the effectiveness of the simulation flat. The comparison between calculation result and experiment result shows that the flat can indicate the unevenness and the asymmetry of the heat transfer through walls and the air flux and temperature out of the air supply holes on the air distribution system. The calculation error of velocity and temperature is 15% and 6% respectively, which proves that the flat has rather high precision and engineering value.
