Patterns of Drop Impact onto Intermediate-Heighted Pools: Fingers, Rings, and Flowers

ORAL

Abstract

What happens when a drop impacts a pool with a depth comparable to the drop's diameter? Through high-speed imaging, our experiments reveal three categories of patterns: fingers at lower impact velocities, flowers at higher impact velocities, and stagnant rings in between. Recent observations will be reported in this talk, together with our characterization by scaling analysis.
