利用计算流体力学(CFD)软件对平板太阳能集热器的水流问题进行了模拟分析。考虑的案例包括太阳辐射的CFD建模以及集热器的管表面、玻璃盖、侧壁和隔热底座之间的混合对流和辐射传热模式以及管内循环水中的混合对流换热以及底座和管材料之间的传导。在获得集热器主体体积上的 3-D 温度分布后，对有和没有循环水流的情况下的集热器性能进行了研究。建立了实验模型并进行实验来验证CFD模型。将出水温度与实验结果进行比较，吻合较好。
The problem of flat plate solar energy collector with water flow is simulated and analyzed using computational fluid dynamics (CFD) software. The considered case includes the CFD modeling of solar irradiation and the modes of mixed convection and radiation heat transfer between tube surface, glass cover, side walls, and insulating base of the collector as well as the mixed convective heat transfer in the circulating water inside the tube and conduction between the base and tube material. The collector performance, after obtaining 3-D temperature distribution over the volume of the body of the collector, was studied with and without circulating water flow. An experimental model was built and experiments were performed to validate the CFD model. The outlet temperature of water is compared with experimental results and there is a good agreement.
