Directional motion of vibrated sessile drops: A quantitative study
Maxime Costalonga, Philippe Brunet
Abstract
Slanted vibrations are known to induce directional motion of sessile drops. A quantitative investigation into the influence of the amplitude, frequency, and inclination of vibrations, as well as the liquid viscosity, finds that the rectified motion velocity increases quasilinearly with the forcing amplitude. This is not predicted by existing theories and offers challenging questions for future investigations.
