Water spring: a model for bouncing drops
arXiv:cond-mat/0212151 · doi:10.1209/epl/i2003-00340-1
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.
