ANSYS Fluent a finite volume code has been used for axisym-<br /> metric model of the solar chimney power plant (SCPP) prototype in Manzanares,<br /> Spain considering updraft tower. A standard k- turbulence model and Boussinesq<br /> approximation for buoyancy driven flow is considered. Small pressure difference because of natural draft inside the chimney during day time has been observed due<br /> to solar radiation. The numerical results obtained for average velocity and temper-<br /> ature at chimney inlet are validated with the experimental results of the prototype.<br /> It has been observed that both the velocity and temperature of air inside the SCPP<br /> increases significantly with the increment in solar radiation. Increase in the chimney<br /> height and collector radius also increases the power output of the plant. The effect<br /> of chimney convergence with different area ratio on the power output of SCCPs have<br /> been analyzed https://jser.ut.ac.ir/article_70911_2c28d223baab3f21a96ce4b643e18299.pdf
