Design, Fabrication And Test Of Variable Height Solar Chimney

Solar chimney has been used for both power generation and enhancement of natural ventilation purposes. Its working principle has been discovered during the early years and has been used mainly for ventilation purposes. Solar chimney power generation concept is very much based on the air updraft, which would rotate the wind turbine located at the base of the chimney. In large power plants, the collector region could spread across the whole field in order to obtain a higher air temperature difference between the ambient and the working fluid which would then better induced the updraft. The objective of this study revolves around the parameter – variable canopy height and chimney height which would affect the performance of the collector and thereby the system.
