摘要
在对车厢内热环境进行理论分析的基础上,建立了经常处于太阳辐射的工作状态的现代某客车车厢的数值模型。综合考虑传导、对流及辐射传热,采用标准k-ε两方程湍流模型及各种辐射模型,对典型太阳辐射下客车车厢内温度场进行了稳态数值计算,为客车车厢内气流组织和热环境优化的研究提供依据。
Based on the theoretical analysis on thermal environment of coach compartment, a numerical model for the compartment of modern coach often exposed to solar radiation is established. By comprehensively considering heat transfer by conduction, convection and radiation and using standard two-equation turbulence model and various radiation models, a steady-state numerical calculation on the temperature field of coach compartment under typical solar-radiation is conducted, providing a basis for the research on the air flow management and the thermal environment optimization of coach compartment.
