Abstract

The COMSOL Multiphysics software was used to study numerically the effect of feedback control on convective flow within a square region filled with a fluid-saturated porous medium. The left side wall is heated and the right side wall is cooled, while the horizontal walls are kept adiabatic. Heat is generated internally within the porous medium at a rate proportional to a power of the temperature difference. The Darcy model is used in the mathematical formulation for the porous layer. A sensor array is embedded at the fluid's mid-width enclosure and actuators are located on the heating side. It was found that the flow intensity and the space average within the convective region can be suppressed by the feedback control.
