摘要

In this work, a semi-empirical model and 2D numerical model were developed to evaluate the Solar Chimney Power Plant (SCPP) efficiency in Chief, Algeria. The airflow through the solar chimney is treated as a compressible flow in contrast to the Boussinsq model. In addition, the pressure and temperature in the solar are considered not constant. Thus, modelling was carned by means of Renolds Averaged Navier-Stokes (RANS) equations coupled to the k-ε turbulence model. The meteorological parameters used in this study such as the temperature and the global solar radiation were measured in the Chief region, Algeria, during 2018. The power output, updraft velocity and temperature were calculated and compared with the experimental results obtained from the Manzanares prototype to validate results of the compressible flow through the solar chimney obtained with the 2D numerical model are more accurate than those produced by Bossinsq model. The COMSOL Multiphysics software was used in this study to simulate the SCPP flow behaviour. Results demonstrate that the proposed numerical model derived from fundamental engineering calculations is reasonably accurate and can be effectively applied to investigate the SCPPs efficiency.
