摘要(Abstract):

应用CFD方法建立了A320飞机头等客舱内环境和人体的三维模型,对客舱内流场进行仿真分析,分析了在不同送风速度时的温度场、速度场。以客舱内的空气分布特性指标(Air Diffusion Performance Index,ADPI)作为热舒适评价依据。在靠近人体附近的6个横截面上,采集人体头部高度的温度值和风速值,由这些采集到的数据计算客舱内的。计算不同送风速度下客舱内的,对计算结果进行描点和非线性曲线拟合,得出客舱内与送风口速度的函数关系,为客舱空调控制提供理论依据。
By the application of CFD method,the three-dimensional model of A320 aircraft in the first class cabin and the human body was established. Analysis was carried out on the flow field inside the cabin. The simulation analyses the temperature field,velocity field at different supply air speed. The thermal comfort evaluation in the cabin is on the basis of Air Diffusion Performance Index. It is collected the temperature and wind speed value at the human head's height on the six cross section near the body to calculate the cabin's. The calculation results were tracing point and non- linear curve fitting,and it is concluded that the cabin's as a function against the velocity of air supply outlet,providing theoretical basis for the cabin air conditioning control.
