Genetic Algorithm Optimization of the Performance of a Solar Chimney Power Plant

it is necessary to optimize the structural parameters of a built solar chimney pilot plant in Kerman. There can be selected five main design parameters that affect the performance of solar chimneys: collector radius, collector slope, collector inlet height, chimney height and chimney diameter. This paper presents an optimization of a solar chimney power plant using genetic algorithms. The two-objective design to simultaneously maximize the two conflicting objectives including power output and collector efficiency is used. Based on this approach, obtaining the best combination of the possible geometrical parameters, performance of the Kerman pilot is improved. In addition, in order to consider the effects of the design variables on the collector efficiency a parametric study was presented. Moreover, slope and inlet height of the collector are optimized. The results showed that slope and inlet height of the collector have a significant effect on the collector efficiency.
