Applying response surface method to optimize the performance of a divergent-chimney solar power plant
Abstract
One of the effective tools to generate electricity from solar energy is Divergent-chimney solar power plant (DSPP). Divergent and cylindrical chimneys of solar power plants have different performances considering turbine pressure drop ratio (ft). For the first time, the divergent angle (DA) and solar radiation (SR) interaction effects on 〖ft〗_opt are discussed through applying the Computational Fluid Dynamics (CFD) and Response Surface Method (RSM). FLUENT software is employed to perform 2D axisymmetric numerical stimulation for the Manzanares prototype. The DA, SR, and ft with ranges of 0°-3°, 200-800 W/m2, and 0.2-0.9 are considered, respectively, in the RSM optimization. The outcomes denote that the amount of 〖ft〗_optvaries from 0.71 to 0.89 continuously, and it is related inversely to the DA and directly to the SR. The maximum efficiency 〖(η〗_max) is obtained at 〖ft〗_opt, for different SRs and DAs. It is concluded that the η_max is enhanced from 0.42% to 0.50%, achieved by increasing the DA and SR values. Furthermore, the quadratic correlation of the 〖ft〗_opt and η_max in terms of DA and SR parameters are provided. Therefore, the consequences of this research would be a suitable resource for designing optimum turbines for the DSPPs.
