Abstract

A fluid layer subjected to an internal heating source and cooled from above and below is studied. Using linear stability analysis and numerical simulation it is shown that the critical Rayleigh number related to the bifurcation from the motionless conductive state to a convective state can be increased by controlling the heating power. A feedback-control strategy using the deviation of the real fluid temperature from that of the associated conductive state is applied for this purpose. (C) 2002 Elsevier Science Ltd.
