Improving the Gained Power from Solar Chimney by Changing Radius and Height

Abstract

This paper evaluates the influence of changing the chimney height and Tower outlet radius and base area on the performance of solar chimney power plant. Results indicate that the chimney height and Tower outlet radius and base area are very important parameters for improving the gained power. In this paper CFD technology is used to investigate the changes in flow kinetic energy caused by the variation of tower flow area with height. It was found that the tower area change affects the efficiency and mass flow rate through the plant. So By changing collector area, chimney tower radius and height it can possible to get maximum efficiency with small change in design of SCPP. Also the simulation convenient to predict the performance of the solar chimney and that can save the cost of the experimental procedures .
