Abstract:Vibration affects the wetting behavior of droplets, and
it is feasible
to use vibration to modulate the adhesion characteristics of droplets.
In this paper, the effect of vertical sinusoidal vibrations on the
wettability of molten aluminum droplets on the substrate surfaces
of smooth and with nanopillars is investigated. The increase in the
frequency or amplitude of the vibration leads to a rise in the interfacial
potential energy between the molten droplets and the substrate, which
in turn leads to the occurr… Show more
