建立了单通道民用飞机客舱气流组织数值仿真模型,对不同的送风角度、送风速度和送风比例等状态的客舱气流组织进行了数值仿真研究,通过对比分析不同状态的仿真结果的流场、温度场、预期不满意百分率PPD、预测平均反应PMV、吹风感所引起的不满意率DR及其垂直温差导致的不满意率PD等热舒适性参数,发现水平角度送风、上风口较低风速和下风口较大风速、上风口风量少于下风口的设计较为合理。
The numerical simulation analysis model of air distribution in single-aisle cabin civil aircraft is built. The flow field, temperature filed, PMV, PPD and DR are calculated and analyzed at different air-supply angle, different air-supply velocity and different air proportion between the high outlet and low outlet. The results show that horizontally supplying air at the low and high outlet, high velocity for low outlet and low velocity for high out- let, and more air for low outlet and less air for the high outlet are suitable.
