Abstract

The normal impingement process of two water droplets upon a thin film on the solid surface was numerically investigated. The numerical treatment was based on the finite volume solution of the Navier-Stokes (N-S) equations combined with the volume of fluid method (VOF). Physically reasonable results for the process of two droplets impacting on the thin film were obtained. The effects of the droplet velocity, the film thickness and the spacing between the two droplets on the splash and spread process of the impact were examined.
