MIXING OF TWO FLUIDS IN A VERTICAL ENCLOSURE WITH OPPOSED BUOYANCY FORCES
RESUMO
The mixing characteristics of two fluids under opposing thermal and solutal buoyancy forces are investigated with a two-fluid model. Transport equations are solved for the zone-averaged variables of each fluid with allowance for interface transfer of momentum and energy. The effects of thermal and potential-energy driven convection and Prandtl number are investigated. The mixing width and heat transfer rate significantly increase with the Grashof number. The interface deforms into multiple waves at low buoyancy ratio and a single wave at high ratios. As Prandtl number increases, a whorl interface structure is replaced by a tendril structure of larger mixing area.
