- Abstract
This paper presents a numerical study of natural convection and entropy generation in a cubic cavity fitted by a baffle plate. Three-dimensional analysis has been done by solving governing equations with a written computational code in FORTRAN based on FVM. The study was performed for two configurations related to the position of the baffle. The first one was carried for a baffle plate attached to the upper wall of the cavity although the second case was reserved for a baffle attached to the down face. The results are given for Rayleigh number (Ra=105), Prandtl number (Pr = 7.1) and baffle length (d = 0.5). The influences of baffle position on flow structure, temperature distribution, and heat transfer and entropy generation are presented.
