摘　　要：建立了全玻璃太阳能真空集热管流场和温度场的FLUENT计算模型,设置适当的边界条件后经计算,温度场与实验结果有非常好的拟合性.利用FLUENT的计算,可视化地揭示了太阳能真空集热管闷晒下的流场和温度场的变化规律,还计算了各部分的热损失流量.In this article the FLUENT compute model of all-glass evacuated solar collector tube is constructed according to a physical model and the interface of FLUENT. The boundary conditions are established on the basis of the data of three different states of water stagnation. The calculation results have a good match with the test results. By FLUENT, we can graphically observe the variation in fluid field and temperature field during covered solarization of solar collector tube and obtain the data of heat loss by different ways.
