The effect of using phase change materials and cavities on the solar chimney power plant collector

In order to evaluate the performance of the solar chimney power plant, simulations for thermal radiation of ۷۰۰, ۱۰۰۰, and ۱۳۰۰ W/m۲ have been conducted. The simulation has been carried out with the help of computational fluid dynamics. The results reveal that with increasing heat flux, the output power increases. Beyond that, the solar power plant with rectangular cavities produces ۳۰%, ۳۲%, and ۲۱% more power than the triangular case at heat fluxes of ۷۰۰, ۱۰۰۰, and ۱۳۰۰ W/m۲, respectively. In addition, paraffin wax phase change materials have stored solar energy for use in the absence of radiation.
