| 摘 要： | 对包含人体的3维空调车室内部空气流动的速度分布和温度分布进行了数值计算.采用集总参数法建立人体模型,将该模型计算出的人体表面温度作为CFD(computational fluid dynamics)计算的边界条件,从而更细致地考虑了散热量在人体表面的分布情况.CFD计算采用六面体网格、SIMPLE算法,考虑了自然对流换热和固体壁面间的辐射,应用整体求解法计算车内传热问题.针对一款实车的试验,证明了计算的准确性.

| Abstract: | Simulation of the thermal environment in a vehicle cabin with passengers is performed in this paper. Boundary temperatures for CFD calculation are provided by numerical human model created with lumped-heat-capacity method. In the CFD simulation, hexahedral mesh and SIMPLE algorithm is applied. Natural convection and wall radiation are taken into consideration. An experiment on a real car is executed to validate the simulation. |
