为了研究塔式太阳能多孔介质吸热器的传热传质特性,建立吸热器稳态传热模型,选择适合多孔介质太阳能吸热器的体积对流换热系数模型,采用数值方法求解,并分别分析孔隙密度、孔隙率和入口空气速度对温度场的影响。文中技术可以为同类型太阳能吸热器的设计和改造提供参考。
In order to investigate the heat transfer characteristics of a porous media solar power tower plant receiver, this paper proposes the mass and heat transfer models in the porous media solar receiver, chooses the preferable volume convection heat transfer coefficient model, solves these equations by the numerical method, and analyzes the typical influences of the cell density, porosity, air inlet velocity on the temperature distribution. The paper can provide a reference for this type of receiver design and reconstruction.
