Abstract

Inkjet printing, rainfall, droplet collision in combustion chamers are different forms of drop impacts. The whole dynamics of these impacts is complex and remains far to be fully understood. In particular, the role of the viscosity of the drop liquid is still hard to exhibit. Hence, the role of the viscosity for the early time of the impact needs to be elucidated. This paper presents numerical simulations of the impact of a drop on a liquid layer thanks to a volume of fluid technique (VOF), where the Navier-Stokes equations are solved for both liquid and gas phases.
