Summary
Combined simulations and laboratory tests examine buoyancy-driven air and heat transport in a solar chimney, showing that above a threshold Rayleigh number reverse flow cuts ventilation. Placing several discrete heat sources on the glazed wall, with their size, location and number varied, suppresses this backflow and improves airflow compared with a conventional chimney; measured and simulated results agree well.
