摘　　要：用计算流体力学与计算传热学的方法对车室内的非均匀热环境进行了模拟与数值计算。文中首先对车室内的热环境建立了相应的计算模型,然后进行了相应的数值计算。计算中不仅考虑了空气温度、空气流速、空气湿度、太阳辐射和车室内热辐射的影响,而且还考虑了车窗玻璃表面的几何形状、周围物体的物理特性和热特性对车室内热环境的影响。因此该模型可以用于预测车室内不均匀热环境的特性,以便为人体局部热舒适性的评价提供必要的计算数据。This paper simulates and analyzes non-uniform thermal environment in the cabin by means of CFD and computational heat transfer. It first develops computational model for cabin thermal environment, and then makes corresponding numerical simulation. This calculation takes into account not only the character of a highly non-uniform thermal environment as a function of air temperature, air velocity, air humidity, direct solar flux, thermal radiation, but also the effect of the geometrical configuration of the passenger compartment including glazing surfaces, pertinent physical and thermal properties of the enclosure on cabin thermal environment, so as to supply data for evaluating local thermal comfort level of an occupant.
