Abstract

In this paper, the effect of buoyancy force in a square enclosure is studied numerically. The coupled equations of continuity, momentum and energy are solved by a finite difference method. The SIMPLE algorithm is used to solve iteratively the pressure-velocities coupling. The numerical investigations in this analysis are made over a wide range of parameters, Rayleigh number and dimensionless heater lengths. Results are presented graphically in the form of streamlines, isotherms and also with a velocity profiles and average Nusselt numbers.
