Influence of Fluid Flow Regimes on the Performances Analysis of Solar Chimney Power Plants

摘要

The purpose of the work presented in this study is related to the fluid flow analysis andenergy calculation, for the prediction of the chimney power plants performances, such as the power delivered by these devices, according to the Rayleigh number and some geometrical and physical parameters. The Mathematical modelling approach used is based on flows in an opened enclosure. This analysis consists in developing a computer software with dimensionless variables, and in generalized coordinates, in order to simulate an air flow in a chimney, by taking into account different flow regimes. A good agreement is observed between the results obtained by our computer software developed in this study and experimental results on Manzanares site.
