Numerical Simulation on the Characteristic of a Solar Chimney

The air flow and heat transfer performance of a solar chimney with the inclination angle of 30deg was investigated by using numerical method. It was found that there is a correlation between solar radiation and ventilation rate and there is a temperature field under the effect of thermal pressure. The research result shows that in the certain scope of research, the ventilation rate is influenced by solar radiation. With the solar radiation increasing, the temperature of chimney decrease along direction from the heat absorption wall to the glass cover-plate surface, and the air flow speed distribute nonuniform along the channel width direction.
