Three-dimensional multi-relaxation time (MRT) lattice-Boltzmann models for multiphase flow
In this paper, three-dimensional (3D) multi-relaxation time (MRT) lattice-Boltzmann (LB) models for multiphase flow are presented. In contrast to the Bhatnagar-GrossKrook (BGK) model, a widely employed kinetic model, in MRT models the rates of relaxation processes owing to collisions of particle populations may be independently adjusted. As a result, the MRT models offer a significant improveme...
متن کاملHybrid 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 ...
متن کاملMultiple - 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...
متن کاملSimulation of Lid Driven Cavity Flow at Different Aspect Ratios Using Single Relaxation Time Lattice Boltzmann Method
Abstract Due to restrictions on the choice of relaxation time in single relaxation time (SRT) models, simulation of flows is generally limited base on this method. In this paper, the SRT lattice Boltzmann equation was used to simulate lid driven cavity flow at different Reynolds numbers (100-5000) and three aspect ratios, K=1, 1.5 and 4. The point which is vital in convergence of this scheme ...
متن کاملEvaluation of three lattice Boltzmann models for multiphase flows in porous media
A free energy (FE) model, the Shan–Chen (S–C) model, and the Rothman and Keller (R–K) model are studied numerically to evaluate their performance inmodeling two-dimensional (2D) immiscible two-phase flow in porous media on the pore scale. The FEmodel is proved to satisfy the Galilean invariance through a numerical test and the mass conservation of each component in the simulations is exact. Two...
