TRANSPORT PHENOMENA IN NONISOTHERMAL FLOW BETWEEN CO-ROTATING ASYMMETRICALLY-HEATED DISKS

The present paper reports a numerical study on laminar mixed convectio n between two corotating asymmetrically-heated disks. The centrifugal- buoyancy effect is considered by invoking the Boussinesq approximation . To investigate the qualitative features of this class of relation-in duced mixed convection, the classical boundary-layer approximation is employed to predict the simultaneous development of flow and temperatu re fields. Effects of the centrifugal-buoyancy, Coriolis force and asy mmetric wall-heating are then examined based on the numerical results. For a typical through-flow Reynolds number in a stable laminar flow r egime (Re = 500), the threshold, type and location of the flow-reversa l at various rotational and wall-heating conditions are studied. Also, the mechanisms of the flow-reversal phenomena are addressed in detail .
