Gas influence in drop impact on dry solid substrates

Résumé

A numerical study by the code GERRIS of drop impact onto a solid surface is presented. It is shown that under the incompressible assumption, drop impact can still perform different behaviors by changing the density or viscosity of surrounding gas, the splash can be suppressed for small gas density or viscosity and a no-vertical frontier exists between splash and non-splash. It is suggested that some aerodynamic instability can be crucial in the mechanism of splashing.
