The performance of a solar chimney under meteorological conditions of Cairo is studied. A mathematical model simulating the performance of solar chimney was developed. The geometrical and operational parameters were analyzed. Different chimney cover materials were examined. The results showed that the airflow rate was significantly depended on the wind speed as well as the dimensions of chimney.
