Abstract

The solar chimney (SC) was effectuated as a prototype by several engineers and scientists to utilize updraft solar heating. A solar chimney power plant (SCPP) heats the surrounding air using solar radiation when drives a wind turbine-generator unit to produce electrical power. The SCPP has enormous size, produces a remarkable amount of electricity, and thus, reduces the adverse environmental impacts. The dimensions of the SCCP components, such as collector area, the diameter and height of the chimney, etc., should be optimized to achieve the best performance from the energy and exergy points of view. Since exergy is consumed in the SCPP due to irreversibilities, there is a direct relation between exergy and SCPP development. This review paper describes different components of an SCPP, provides general governing equations, and presents mathematical models for energy and exergy analyses. Besides, advances in exergy analysis of SCPP are discussed and future directions are provided.
