Summary
A MATLAB-based mathematical model predicts how well solar chimneys, either tilted on roofs or upright on walls, naturally ventilate buildings, using local weather records from Stellenbosch, South Africa. Various designs are compared by hourly air change rate, examining how tilt, cavity width, height and view factor influence the airflow they deliver.
