Summary
A mathematical model estimates airflow in a small solar chimney by calculating the temperatures of its absorber, channel air and glazing. Tests on a prototype with an absorber under 1 m tall, using three air gap and inlet size combinations, matched the predictions closely; measured velocities reached about 0.24 m/s, suggesting windows could serve as solar chimneys.
