The present paper reports a numerical study on laminar mixed convection 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-induced mixed convection, the classical boundary-layer approximation is employed to predict the simultaneous development of flow and temperature fields. Effects of the centrifugal-buoyancy, Coriolis force and asymmetric wall-heating are then examined based on the numerical results. For a typical through-flow Reynolds number in a stable laminar flow regime (Re = 500), the threshold, type and location of the flow-reversal at various rotational and wall-heating conditions are studied. Also, the mechanisms of the flow-reversal phenomena are addressed in detail.
