Abstract

The unsteady incompressible laminar flow Navier-Stokes equations with the Volume of Fluid (VOF) model are solved to simulate the prompt splashing phenomenon caused by a droplet impinging on a liquid film. By analyzing the computed flow field in detail, the effects of inertial force, surface tension and viscous force on the prompt splashing are determined. Inertial force promotes the creation and development of the finger pattern via the high pressure region generated by impact, and provides the energy for the prompt splashing. Surface tension restrains the prompt splashing via thickening and shortening the finger pattern. Viscous force can restrain the prompt splashing by reducing the flow inertia.
