| 目的 全面获得车舱流动传热分析的流场和温度场分布。方法 以某车辆舱室为研究对象，对车舱进行合理简化，建立空气流动与传热的计算流体力学（CFD）模型。针对车舱内温度分布特点，采用标准的κ-ε湍流模型描述舱内的空气流动，利用FLUENT软件对车舱在太阳辐射下进行温度场仿真研究。结果 得到了温度场的分布与车载运行时间的变化规律，并利用实车跑车试验结果与仿真结果进行了对比，对比最大误差约为12%。结论 随着外部环境温度的升高，车舱内部温度均呈现梯度变化，不同位置温度差异最大为5 ℃。CFD能为计算和预测温度场分布提供有效的技术支持。 |

| Objective To obtain flow and temperature distribution in flowing heat transfer analysis of vehicle compartment. Methods A vehicle compartment was taken as the research object and the compartment was reasonably simplified. The computational fluid dynamic (CFD) model for computing air flow and heat transfer in the armored compartment was established. Air flow in the compartment was described with the standard κ-ε two-equation turbulence model. With software Fluent, simulation study on the temperature field was carried out for vehicle compartment in solar radiation. Results The relationship between distribution of temperature field and vehicle running time was obtained. The results were compared between the simulation and proving ground test, the maximum contrast error was about 12%. Conclusion With the increase of environment temperature, the temperature of vehicle compartment shows a gradient change, and the maximum temperature difference is 5 ℃ in different position inside the vehicle compartment. CFD can provide technical support for calculation and prediction of temperature field distribution. |
