| 摘 要： | 基于传热学及气象学原理,采用有限元软件ANSYS CFX建模分析热反射涂层路面、普通沥青路面、水泥路面等3种路面的温度场,表明反射率越高,路面表面温度越低;反射率为51%的热反射涂层路面较沥青路面和水泥路面最大降温值分别为9℃和3℃。同时对这3种路面温度进行了实测验证,理论分析与实测结果基本一致。

| Abstract: | Based on heat transfer theory and meteorology,ANSYS CFX,the finite element method,was used to study the temperature field of heat-reflective pavement,asphalt pavement and cement pavement.The results show that the higher the road surface reflectance,the lower the surface temperature of pavement is.The reflectance of heat-reflective pavement,whose reflectivity is 51%,the maximum temperature reduction value can reach 9℃ and 3℃ compared with asphalt pavement and cement pavement.The surface temperature of three types of pavement was also actually measured and the results are in good accordance with the calculating results. |
