| 摘 要： | 研究了整体式太阳能空气集热器的传热性能,建立了稳态假设下的热量传递物理数学模型;通过CFD软件计算,分析了进口空气流速、空气温度、太阳辐照强度对集热器传热性能的影响;计算结果表明:集热器的集热效率随工质流速的增大而增大、随进口温度的升高而下降、随太阳辐照度的波动很小,受太阳辐射强度的影响不大。

| Abstract: | A physical mathematical model based on steady-state assumption is developed to study the heat transfer characteristics in the integral solar air collector.Through the CFD software is applied to numerical simulation,the effect of various parameters such as the inlet air velocity,air temperature and the intensity of solar radiation of the air heater are analyzed.It is discovered that thermal efficiency increases with increasing air velocity and decreasing temperature of inlet air,on which the solar radiation intensity have little influence. |
