Modeling of Steady Natural Ventilation in Solar Chimney

Abstract:

Article Preview

A revised one-dimensional steady model was proposed to improve the prediction of the natural ventilation performance in a solar chimney. The thermal resistance of the glass cover and absorber wall was taken into account to calculate the heat transfer between the air and the glass cover or absorber wall in the model. The present model results were compared to the related experimental data and reasonable agreement was validated. Comparison of the results also showed that the present revised model was able to predict the mean temperature of air in the channel, the air mass rate and heat collection efficiency more preciously than the original model.
