Abstract
The computation of multiphase flows presenting high density ratios, where the
fluids involved are considered immiscible, are of great importance for fundamental
physics and industrial applications; such as the study of liquid-gas interfaces, wave
motion, simulation of bubbly flows and atomization, injection in diesel engines,
chemical processes and others.
This work presents and analyzes a collocated and staggered finite-volume mesh
discretizations suitable for three-dimensional unstructured meshes, which are able
to simulate immiscible multiphase flows with high density ratios. More over, these
mesh schemes numerically conserve mass and momentum while minimize errors
in the conservation of kinetic energy.
Keywords: collocated, conservation, multiphase, Navier–Stokes, staggered.
