摘要： 对某型号教练机座舱在不同进气温度方案下的气流组织进行了数值模拟，研究舱内空气湿度、人体散热率和衣服热阻等因素的影响，获取了座舱内速度场和温度场分布。通过数值模拟所得到的速度场和温度场，改进了Fanger的舒适性假设中人体表面对流散热损失的计算方法，并取得了不同工况下座舱的热舒适性指标。这可为座舱环控系统的优化设计和不同热环境条件下的运行控制提供理论依据。

关键词: 座舱, 气流组织, 舒适性

Abstract: Numerical simulation is carried out to study the flow field and thermal fields inside a training-plane’s air-conditioned cockpit under different air inlet conditions. Effects of air humidity, thermal dissipation of the pilots, and thermal resistance of cloths are investigated. With the obtained flow and temperature fields, we have improved the calculation method for convective heat transfer on human surface based on Fanger’s thermal comfort model. The human thermal comfort indexes are obtained. The numerical results provide a guide to the design and optimization of air-flow in cockpit to control human thermal comfort for different thermal environments.

Key words: cockpit, flow and thermal fields, human thermal comfort
