Objective To establish a complete heat transfer boundary condition model in a cockpit including the inner wall heat transfer boundary condition and the air supply heat transfer boundary condition of the air distribution system.
目的建立较完整的歼击机座舱传热边界条件计算模型,包括内壁面传热边界条件和空气分配系统供气传热边界条件。
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.
根据歼击机座舱内空气流动和传热的特点,建立了座舱内壁面传热边界条件计算模型和空气分配系统供气边界条件计算模型,在此基础上建立了歼击机座舱流场和温度场数值仿真平台,并利用地面模拟实验验证了仿真平台的有效性。
