NUMERICAL ANALYSIS OF THE SOLAR CHIMNEY POWER PLANT WITH ENERGY STORAGE LAYER
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/m2 to 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.
