Control of Convection Patterning and Intensity in Shallow Cavities by Harmonic Vibrations

In this article the interplay among different types of flow (i.e. induced by driving forces of a different nature) is presented as a possible and natural means to control convection patterning and strength in shallow rectangular cavities of finite extent (A =length/height =4) filled with a low Prandtl number liquid (silicon, Pr =0.01). A variety of results concerning the possible spatial structure of the mixed states of steady Buoyant, Marangoni and Vibrational convection are discussed with the express intent of supporting the optimization of future experiments to be performed onboard the International Space Station.
