Relation of change in geometrical parameters in the thermal performance of solar chimney

Summary

Simulations based on the Manzanares prototype in Spain, validated against Haaf's measurements, examine how altering chimney height, chimney diameter, collector radius and collector roof height affects airflow in a solar chimney. Raising the roof lowers performance, whereas the other enlargements raise air velocity; with a wider chimney, turbines work better at the collector exit than inside the tower.
