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.

Journal of Thermal Science and Technology, 2013 We numerically investigate the effect of thermocapillary convection on melting and deforming processes of Phase Change Material (PCM) subjected to local heating. Mass, momentum and energy conservation equations are solved in a 2-D system based on a fixed

Computational fluid dynamics applied to gas-liquid contactors. [PDF]
, 1997 In this paper a `hierarchy of models¿ is discussed to study the fluid dynamic behaviour of gas-liquid bubble columns. This `hierarchy of models¿ consists of a Eulerian-Eulerian two fluid model, a Eulerian-Lagrangian discrete bubble model and a Volume ...
