Short-term oscillation and falling dynamics for a water drop dripping in quiescent air

Abstract

The short-term falling dynamics of a dripping water drop is studied by simulation and experiment. The pinching dynamics introduces a nonlinear multimode oscillation. A complex transient flow around the drop is induced by the interaction between the falling motion and the shape oscillation.
