Summary
Laboratory tests on a small solar chimney built in Kirkuk, Iraq, varying the heat flux on the heated plate and the width of the air channel. The narrowest gap (3 cm) gave the fastest inlet airflow, about 2.3 m/s, and the best thermal efficiency, near 25%, at the highest heat input. The widest gap gave the highest chimney efficiency.
