Abstract
The simulation of multi-phase flow with moving interfaces is important in a wide range of applications, such as ink-jet printing, metal depositions, spray cooling, and biomedical engineering applications. Level Set and Phase Field methods are two well-known techniques for tracking the moving interfaces. Each model has its own strength and weakness. This paper compares the two surface tracking models in the simulation of droplet impingement process. The simulations are carried out by employing the Level Set and Phase Field models in COMSOL. The dynamic impingement processes is presented for a glycerin droplet impacting a non-wetting wax surface. The simulated spreading factor and apex height are compared with experimental results for the two surface tracking models.
