Abstract

The natural convection of air in a square cavity with horizontal temperature and concentration gradients which give opposing buoyancy forces near the vertical walls was studied numerically. The basic equations solved are the continuity equation, the Navier-Stokes equations, the energy equation and the concentration equation. Computations were carried out for Prandtl number Pr=0.71, aspect ratio A=\, Rayleigh number Ra=\Q*, buoyancy ratio ( = solutal buoyancy / thermal buoyancy) N= 2 and various Lewis numbers
