This article presents a numerical study concerning conjugate heat transfer across a vertical rectangular water-filled enclosure divided by multiple horizontal fins. The objective of the study is mainly to explore the effects of the conducting horizontal fins on heat transfer due to conjugate natural convection-conduction in the finned enclosure. Numerical results via a finite-difference method for the governing differential equations of the problem considered have been obtained for two different conductive fins with Ra = 103 to 107, AR = 1,5,8, and 10, N=1 to4, t=0.00001 to 0.125. The results demonstrate that the feasibility and effectiveness of using horizontal fins to enhance heat transfer across a vertical rectangular enclosure depend strongly on the aspect ratio, the Rayleigh number, the thermal conductivity, and the number of fins in the enclosure.
