Summary
In this paper, we present a computational study concerning the problem of buoyancy-driven flows in a shallow cavity with aspect ratio, Ar = 4. We investigate two cases with rigid and free-surface upper boundaries. For each of these cases, the effects of Grashof number is investigated for low Prandtl number fluids, namely Pr = 0 (conduction limit) and Pr = 0.015. The numerical results indicate the onset of oscillatory flow as well as some sudden transitions at higher Grashof numbers.
