Splash control using geometric targets

TL;DR

This study demonstrates how geometric targets influence water droplet splash dynamics, allowing precise control over splash patterns and breakup through boundary shape effects observed with high-speed imaging.

Contribution

The paper introduces a novel approach to controlling droplet splashing by using geometric boundary targets, highlighting the role of shape in splash behavior.

Findings

Geometric boundaries significantly alter splash patterns.

Finger formation and breakup are controllable via target shape.

High-speed imaging reveals detailed splash dynamics.

Abstract

Experiments of water droplets impacting small geometric posts of equal dimension to the drop diameter are shown in this fluid dynamics video. High speed photography shows that the dynamics of drop splashing are significantly affected by the geometrical boundary of the target and that finger formation and drop break up are accurately controlled.
