Summary
A rooftop solar chimney prototype at the University of Arizona, with a 5.9 m tower and a collector of about 4 m radius, was instrumented with thermocouples and a traversable hot-wire anemometer to map air temperature and velocity beneath the collector. Companion high-fidelity simulations reveal streamwise flow structures near the collector exit, probably caused by a buoyancy-driven instability.
