Turbulent Flow Calculations of Mixed Convection in a Periodically-Ribbed Channel

RÉSUMÉ
Turbulent mixed convection in a periodically-ribbed channel is numerically investigated. A computational procedure relevant to the fully-developed state is devised by employing a low Re k−ε model of turbulence with a streamline-curvature correction scheme, thus enabling accurate predictions of complex turbulent flow and heat transfer in a ribbed channel. For test cases dealing with forced convection situations, computed results are in good agreement with previous numerical and experimental data. A systematic assessment is made of the effects of buoyancy on the characteristics of flow and heat transfer. Much enhancement in heat transfer takes place when the relative magnitude of buoyancy is large. It also increases the pressure drop in the channel as a manifestation of intensified vertical motions in the flow field formed between ribs.
