Comparative Numerical study of the Thermal and Electrical Performance of Combined and Separated Solar Chimneys for Passive Space Cooling in Multi-Storey Buildings Doubik Yemboate Lare; Yawovi Nougblega; Kokou Dowou; Kokou Amenuvela Toka Simulations compare single, combined, separated and shunt photovoltaic/thermal solar chimneys for passively cooling multi-storey buildings, using a mixed-convection model solved by finite differences over a range of Reynolds numbers.

Summary
Simulations compare single, combined, separated and shunt photovoltaic/thermal solar chimneys for passively cooling multi-storey buildings, using a mixed-convection model solved by finite differences over a range of Reynolds numbers. Multi-inlet layouts remove heat more effectively and keep PV electrical output steadier, while the separated design divides the airflow, spreading temperature more evenly across the cells and cooling them better.
