Optimizing thermal management in buildings: the role of mixed convection and solar chimneys Mahmoud Kalfali; Mouna Maache Battira; Nourredine Belghar; Chihab Eddine Brahmi Finite element simulations in COMSOL model a heated thermal chimney attached to a multi-storey building under mixed convection, for Grashof numbers between 103 and 106. Heat transfer, measured by the Nusselt number, improves as buoyancy grows, and the location and dimensions of the chimney and inlet strongly influence performance, suggesting well-designed geometry could cut reliance on mechanical cooling.

Summary
Finite element simulations in COMSOL model a heated thermal chimney attached to a multi-storey building under mixed convection, for Grashof numbers between 10³ and 10⁶. Heat transfer, measured by the Nusselt number, improves as buoyancy grows, and the location and dimensions of the chimney and inlet strongly influence performance, suggesting well-designed geometry could cut reliance on mechanical cooling.
