Dynamics of thin liquid films falling on vertical cylindrical surfaces subjected to ultrasound forcing.
Axial ultrasound forcing applied to a vertical cylinder is shown to affect a gravity-driven flow of a thin liquid film on its outer surface. In the case of larger forcing amplitudes, we find that the film flow can be completely stopped.
