Summary
Simulations of a solar chimney fitted with an RT-42 phase change material and fin unit, modelled with an effective heat capacity approach and checked against measurements, over a wide range of heat fluxes. Performance drops steeply at or below 500 W/m² and improves little above 700 W/m², so it depends strongly on solar input. Thermal conductivity enhancers could help under weak radiation.
