TLDR
In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.About:

An Efficient Method for Capturing Free Boundaries in Multi-Fluid Simulations
Feng Xiao,Akio Ikebata +1 more
TL;DR: In this paper, an easy-to-use front capturing method is devised by directly solving the transport equation for a volume of fluid (VOF) function, which can be directly used to compute the VOF-like function and retain the compact thickness of the moving interface in multi-fluid simulations.

Development of a compressive surface capturing formulation for modelling free‐surface flow by using the volume‐of‐fluid approach
TL;DR: This study presents the development of a new volume-of-fluid free-surface capturing formulation that reduces the numerical smearing of the interface associated with explicit higher resolution schemes while limiting the contribution of the artificial compressive term to ensure the integrity of the interfaces shape is maintained.

Numerical study on the effects of non-dimensional parameters on drop-on-demand droplet formation dynamics and printability range in the up-scaled model
Eunjeong Kim,Jehyun Baek +1 more
TL;DR: In this paper, the printability range of a drop-on-demand printhead is determined by a Z number, which is the inverse of the Ohnesorge number (Oh), but it is found that the Z number alone is insufficient for describing the droplet formation dynamics.
