| 中文摘要: |
| 散热器是汽车发动机冷却系统的重要组成部分.采用多孔介质模型对汽车散热器进行简化，对其温度场和流场进行了仿真计算.分别模拟计算了进、出水口位置以及水管排数不同时散热器的换热性能，分析比较了它们的换热特性和流动特性以获得进、出水口位置及水管排数对管带式散热器性能的影响，研究了散热器结构优化的方向.利用风洞试验台进行了试验，并将试验值和数值模拟值进行了对比分析，验证了数值模拟的正确性. |

| The radiator is one of the key parts of automotive engine cooling system.In this paper,a simplified porous medium model for automobile radiators was established to simulate the temperature and flow fields of the automobile radiator.Heat transfer performance of the radiator with different water-inlet and -outlet positions,and different tube row numbers was simulated.The effect of water-inlet and -outlet positions,and different tube row numbers on the heat transfer performance of the radiator was discussed.Experiments were carried out using a wind tunnel setup.A comparison between the experimental data and the simulation results was made to verify the accuracy of the numerical simulation. |
