摘要
空调车室内空气的速度场、温度场研究是空调车室内气流组织设计及车室内舒适环境评价与研究的基础．空调客车运行环境恶劣，太阳辐射作用及复杂的车室内部结构等直接影响客车室内的温度场与空气速度场分布．采用κ－ε紊流模型及贴体坐标，应用整体求解法计算了空调车室内气固耦合传热问题，采用ＭｏｎｔｅＣａｒｌｏ法分析计算了太阳透射辐射在车室内各固体表面引起的附加热流变化，并以此作为能量方程的附加源项，对空调客车室内三维空气流场与温度场分布进行了数值模拟研究。
By bodyfitted coordinate and κ ε turbulence model, the indoor air/solids fluid flow and heat transfer conjugated problems were resolved by the whole method. The effect of solar radiation was taken into account by means of the Monte Carlo method and this auxiliary heat flow on the faces of the indoor solids is the source term of the energy equation. The 3 D distributions of the airflow and temperature fields in the chamber were numerically calculated. It gave a basis for the comfortable environment in the air conditioning compartment.
