MIXED CONVECTION IN A LOW ROTATION HORIZONTAL CYLINDER

In this paper, the effect of rotation imposed to a horizontal cylinder containing a fluid is studied. A uniform temperature is imposed on th e circular boundary of the enclosure while a uniform internal heat sin k is applied to cool down the system. The resulting convective heat tr ansfer is studied using both perturbation methods and numerical proced ures. Only the weak rotation regime, in which the centrifugal force is negligible compared to gravity, is considered. Results indicate that the rotation significantly affects the flow and temperature fields, an d thus the overall heat transfer. (C) 1998 Elsevier Science Ltd.
