Abstract
The purpose of the current study is to conduct an experimental investigation into the effects of ambient temperature and solar radiation on the mean temperature of the absorber and collector of the solar chimney.To achieve this goal, a solar chimney prototype with a collector diameter of 0.79 m, a collector height of 0.105 m, a chimney diameter of 0.075 m, and a chimney height of 1.39 m was constructed at M'sila University.The experiments were conducted in a arid climate at the Biskra University.The results show that the mean absorber temperature was higher than the mean collector temperature.The absorber and collector temperatures are correlated by a polynomial law.The ambient temperature and solar radiation have a significant impact on the mean temperature changes of the absorber and collector.Mathematical models that depict how the mean collector and mean absorber temperatures change with respect to solar radiation and ambient temperature have been proposed.
