Vibration-driven mass transfer and dynamic wetting

This review is devoted to the physical mechanisms enabling dynamic wetting effects following the transport of mass in droplets and films that are exposed to external mechanical vibrations. The essential nonlinear nature of the transport mechanisms is emphasized. Specifically, we discuss the transport of mass and dynamic wetting effects due to (a) the innate nonlinearity of the conservation equations governing the flow of liquid and (b) the nonlinear motion of the three phase contact line. Special attention is payed to the contribution of high frequency mechanical vibrations to dynamic wetting, observed in the course of the past decade, as well as to parametric resonance and its catalytic contribution to vibration-driven mass transfer.
