RT Journal Article ID 1b967cbd457ca817 A1 Jani, Saeid A1 Amini, Meysam A1 Mahmoodi, Mostafa T1 Numerical Study of Free Convection Heat Transfer in a Square Cavity with a Fin Attached to Its Cold Wall JF Heat Transfer Research JO HTR YR 2011 FD 2011-11-16 VO 42 IS 3 SP 251 OP 266 K1 natural convection K1 numerical method K1 square cavity K1 thin fin AB Fluid flow and natural convection heat transfer in a differentially heated square cavity with a fin attached to its cold wall is investigated numerically. The top and the bottom horizontal walls of the cavity are insulated while the left and right vertical walls of the cavity are maintained at a constant temperature Th and Tc, with Th > Tc, respectively. The governing equations written in terms of the primitive variables are solved numerically using the finite volume method and the SIMPLER algorithm. Using the developed code, a parametric study is performed, and the effects of the Rayleigh number, length of the fin and its position on the flow pattern and heat transfer inside the enclosure are investigated. The results show that for high Rayleigh numbers, a longer fin placing at the middle of the right wall has a more remarkable effect on the flow field and heat transfer inside the cavity.
