| 摘 要： | 采用试验与数值模拟相结合的方法对冬季夜间乘员舱内热环境不均匀性进行了研究,得到不同送风模式下乘员舱内温度、速度不均匀度.接着基于Stolwijk人体热调节模型,采用Berkeley热舒适评价模型对乘员热舒适状态进行模拟,对比分析了2种送风方式下的人体热舒适性.最后通过对实际送风工况、基于相同送风焓值的等温送风工况以及基于驾驶员前方等效来流的均匀热环境工况的研究,发现在不均匀热环境下人体更易处于不舒适的状态.

| Abstract: | The thermal environment inhomogeneity of the cabin in winter night was studied by the method of combining experiment and numerical simulation. The temperature and velocity inhomogeneity of the cabin in different air supply modes were obtained. Then, based on Stolwijk human thermal regulation model, the Berkeley thermal comfort evaluation model is adopted to simulate the thermal comfort state of passengers, and the thermal comfort under two air supply modes was analyzed. Finally, the actual air supply condition, the isothermal air supply condition based on the same enthalpy and the uniform thermal environment condition based on the equivalent flow in front of the driver were compared and analyzed. It is found that the occupant is more likely to be in an uncomfortable state in an uneven thermal environment. |
