Summary
Unsteady axisymmetric 2D simulations of a large solar chimney plant, with a 1 km tower and a 2.5 km collector radius, examine how the slope of the collector roof affects output. A flatter roof raises output, while doubling the wall heat flux barely speeds up the airflow because vortices forming at the collector inlet hinder air entry and likely reduce efficiency.
