The two vertical walls are heated and cooled and the other two walls are considered adiabatic. A numerical study of this phenomenon was conducted, by solving the complete system of governing equations by a fluent computer code and using the Boussinesq approximation. In order to verify the validity of our results, a numerical confirmation with references is thus obtained. The variation of the dynamic and thermo-convective structures of an airflow was analyzed for an aspect ratio configuration equal to one and for different number of Rayleigh and temperature gradients. The study also confirmed the proportionality of mean Nusselt number and mean heat flux with temperature gradient and Rayleigh number.
