โœฆ Synopsis

The effect of high-frequency translational harmonic vibrations on the onset of thermocapillary convection in a horizontal liquid layer, bounded above by a free surface and below by a solid wall, is investigated by averaging the convection equations. It is shown that longitudinal vibrations have no effect on convective instability. If the direction of the vibration contains a transverse component, and the action of the vibration has a stabilizing effect: the free boundary of a uniform liquid is smoothed and thermal convection of a non-uniform liquid may be suppressed.

The maximum stabilizing effect is obtained for vertical vibrations.

A linear stability analysis was conducted to assess the feasibility of using a feedback control strategy on the onset of Bรฉnard-Marangoni convection in a micropolar fluid. The single-term Galerkin technique was used to obtain the closed-form solution for the Marangoni number M for the onset of conve
