Summary
A mathematical model, validated against published data, simulates a solar chimney ventilating a closed space under Cairo weather conditions. Wind speed and chimney gap strongly affect airflow, while extra height brings too little gain to justify its cost. Year-round air change rates exceed ventilation standards, and replacing the glass outer cover with other materials raises flow while lowering cost and improving safety.
