采用数值模拟的方法分析了带储能层的太阳能烟囱发电系统的传热和空气流动特性。建立了集热器、烟囱和蓄能层的不同数学模型，分析了太阳辐射对蓄能层蓄热特性的影响。模拟结果表明，在太阳辐射量为200 W/m2 ~ 800 W/m2的范围内，储能层的储热率随太阳辐射量的增加先减小后增大，系统内部的相对静压随太阳辐射量的增加而减小，速度随太阳辐射量的增加而显著增大，随着太阳辐射的增加，烟囱出口和储能层的平均温度会显著升高。
Numerical simulations have been performed to analyze the characteristics of heat transfer and air flow in the solar chimney power plant system with energy storage layer. Different mathematical models for the collector, chimney and the energy storage layer have been developed, and the effect of solar radiation on the heat storage characteristic of the energy storage layer has been analyzed. Simulation results show that the heat storage ratio of the energy storage layer decreases firstly and then increases with the solar radiation increasing from 200 W/m2to 800W/m2, that the relative static pressure decreases while the velocity increases significantly inside the system with the increase of the solar radiation, and that the average temperature of the chimney outlet and the energy storage layer may increase significantly with the increase of the solar radiation.
