Laminar natural convection in an enclosed cavity with differentially heated walls and having fins on the cold wall is investigated. The effect of the number of fins and their position on the cold wall on heat transfer characteristics is analyzed. Governing equations of continuity, momentum and energy are solved using SIMPLER algorithm. A fuzzy controller with pre-defined set of fuzzy rules is implemented as a guiding mechanism for faster convergence. Relaxation factors are adjusted using fuzzy
