Dense Suspension Splat: Monolayer Spreading and Hole Formation After Impact

Fluid Dynamics 2014-07-30 v3 Soft Condensed Matter

Abstract

We use experiments and minimal numerical models to investigate the rapidly expanding monolayer formed by the impact of a dense suspension drop against a smooth solid surface. The expansion creates a lace-like pattern of particle clusters separated by particle-free regions. Both the expansion and the development of the spatial inhomogeneity are dominated by particle inertia, therefore robust and insensitive to details of the surface wetting, capillarity and viscous drag.
