Summary
A CFD model of a wall-mounted solar chimney is used to test how the size of the computational domain affects predicted airflow and Nusselt number, comparing a domain limited to the air channel with one extended into the surrounding air. Results stay within 1% only when the domain extends beyond 3 gap widths above and beside the channel and 1.5 below its inlet.
