"Wet Drop Impact"


When a fast moving drop collides with a layer of fluid it a produces a splash, a spray of secondary droplets. There is a bewildering variety of splash morphologies and droplet distributions which manifest as the system parameters (droplet size and speed, layer depth, fluid properties) are varied. Despite this complexity, a splash begins with the formation of a sheet-like jet. There are at least two varieties of jets: the large and slow lamella jet and the small and quick ejecta jet. In this talk I will present our progress towards understanding the simplest of splashes, the so-called crown splash, which results from the disintegration of the lamella. I will also discuss our experimental results on the ejecta jet and the role of the surrounding gas on its evolution
