Analysis of natural convection in a square cavity with a thin partition for linearly heated side walls

– The purpose of this paper is to optimize the heat transfer rate in square cavity by attaching fin at the bottom wall.

– The problem is formulated and solved using finite element method. Accuracy of the method is validated by comparisons with previously published work.

– It was found that attaching fin reduces heat transfer rate in the cavity.

– Although the problem is not very original it is important in that many applications have heating on adjacent walls.
