Water spring: a model for bouncing drops

Soft Condensed Matter 2009-11-07 v2 Fluid Dynamics

Abstract

It has been shown that a water drop can bounce persistently, when thrown on a super-hydrophobic substrate. We present here scaling arguments which allow us to predict the maximal deformation and the contact time of the drop. This approach is completed by a model describing the flow inside the drop, and by original experimental data.
