行驶中空调客车隔热厢体结构传热问题三维数值研究

本文以太阳辐射和强迫对流为外边界条件，数值分析了非稳态情况下空调客车以４０ｋｍ／ｈ速度行驶时隔热厢体结构三维温度场及热流分布，与实验结果较好的符合，为了空车室内空气流场温度场及空调负荷的准确计算提供依据，也为空车室内舒适环境的研究奠定基础。

3D Numerical Heat Transfer Analysis on Heat Insulation Structure of Moving Air-conditioned Bus

In this paper, taking the solar radiation and forced convection as the outer boundary condition, the 3-D unsteady temperature field and thermal flow of the bus body are numerically analyzed with the bus moving at 40km/h. The results accord well with the experiment. It provides a basis for the accurate calculation of the airflow and temperature fields and the air conditioning loads and lays the foundation of research on the comfortable environment in the bus passenger compartment.
