Numerical simulation of rising droplets in liquid–liquid systems: A comparison of continuous and sharp interfacial force models
TL;DR: In this paper, a level set based code was developed and implemented in the open-source CFD package OpenFOAM® to prevent volume (or mass) loss during the reinitialisation of the level set function, two methods published recently were used in the code.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
