A momentum-conserving, consistent, Volume-of-Fluid method for incompressible flow on staggered grids [PDF]
, 2018 The computation of flows with large density contrasts is notoriously difficult. To alleviate the difficulty we consider a consistent mass and momentum-conserving discretization of the Navier-Stokes equation.

A Backwards-Tracking Lagrangian-Eulerian Method for Viscoelastic Two-Fluid Flows
Applied Sciences, 2021 A new Lagrangian–Eulerian method for the simulation of viscoelastic free surface flow is proposed. The approach is developed from a method in which the constitutive equation for viscoelastic stress is solved at Lagrangian nodes, which are convected by ...

The stream volume of fluid advection algorithm
ANZIAM Journal, 2009 Summary: The volume of fluid (VOF) method is a powerful tool for modelling the motion of free surface fluid flows. In this paper, a new VOF advection algorithm is presented, termed the stream scheme. The algorithm uses a linear piecewise method for free surface reconstruction, coupled to a unique fully multidimensional method of cell boundary flux ...
