On the analysis of bubble growth and detachment at low Capillary and Bond numbers using Volume of Fluid and Level Set methods
TL;DR: In this article, the growth and detachment of an isolated air bubble injected through a single orifice is considered using four different interface capturing methods, An algebraic Volume of Fluid (VOF) method developed in OpenFOAM®, a geometric VOF method implemented in ANSYS-Fluent®-v13, a Level Set (LS) method in TransAT© software, and a geometric coupled VOF with LS (CLSVOF).

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.
