Multiple - Relaxation - Time Lattice Boltzmann Method for Multiphase Flows with High Density and Viscosity Ratios - 10135

In this paper, the lattice Boltzmann method is reviewed for specific applications to numerical simulation of multiphase flow problems. A thorough literature review regarding the multi-phase lattice Boltzmann method was conducted with special focus on flows with large density and viscosity ratios between the two phases. A multiphase model with the capability of handling large-density-ratios is c...

Hybrid multiple-relaxation-time lattice-Boltzmann finite-difference method for axisymmetric multiphase flows

We propose a hybrid lattice-Boltzmann finite-difference method to simulate axisymmetric multiphase flows. The hydrodynamics is simulated by the lattice-Boltzmann equations with the multiple-relaxation-time (MRT) collision model and suitable forcing terms that account for the interfacial tension and axisymmetric effects. The interface dynamics is captured by the finitedifference solution of the ...

Application of the Lattice-boltzmann Method to Multiphase Flows List of Publications

This work deals with multiphase fluids which are investigated numerically with the lattice-Boltzmann method. Two multiphase systems were studied, namely liquid-vapour flow in paper and shear flow of a non-colloidal and non-Brownian liquid-particle suspension. We simulated the behaviour of liquids in an X-ray tomographic reconstruction of a sample of paper board. For a wetting liquid we consider...
