Collector factor in a solar chimney power plant: CFD analysis for the pilot plant in Manzanares

Solar chimneys are popular systems for their simple structures and clean energy generation. Thanks to its semi-permeable structure, the collector, one of system’s basic elements, transfers solar radiation system. As a result heating system air under collector by passing through it is directed high chimney in centre. During upward movement air, converts into electricity via turbine. Due large estimating amount entering creates great cost. The ideal size therefore important. This study offers recommendation pilot plant Manzanares terms power output. While 59 kW output obtained with radius 122 m reference case, observed that increases 78% when increased 170 area doubled. ratio should be range 1–1.5.
