Abstract
Numerical analysis is presented for buoyancy-induced natural convection from discrete heating inside a rectangular enclosure filled with porous media. The study has been made for Rayleigh number range of 10 – 1000 and aspect ratio of A H =10, 4, 2 and 1. The two vertical walls are heated discretely on the right wall and cooled isothermally on the left wall respectively. The remaining two walls are adiabatic. The distribution of stream function was observed and temperature distributions are presented and analyzed. In addition, the present results are compared with previous researchers and show in good agreement.
