摘要

针对太阳辐射对乘员舱内部热环境影响较大的问题,根据雷诺平均(RANS)的方法,采用射线追踪的方法计算了太阳辐射对乘员舱内部温度场的影响,并定量地分析了隔热玻璃的使用对乘员舱温度场的影响。计算结果表明太阳辐射和人体散热对车内温度场均存在明显的影响,采用隔热玻璃能有效地降低太阳透射辐射强度,使得太阳透射辐射平均强度降低了14.4%,仪表盘区域的最高温度降低了3.5℃。研究结果为乘员舱内部热环境的优化提供了新的思路和手段。

Abstract

Since solar radiation has a great impact on the thermal environment,three dimensional temperature field of the passenger compartment was simulated by using ray tracing method based on RANS methods. The influence of the insulation glass on the passenger compartment temperature was also quantitative analyzed. The result of calculation shows that solar radiation and body heat flux have a significant impact on the temperature field inside the cabin. The application of the insulation glass can reduce the maximum intensity of the solar transmitted radiation by 14. 4 percent,consequently make the maximum temperature of panel area decreased by 3. 5 centigrade. The research results can be applied to optimize the thermal environment of the passenger compartment.
