Entropic lattice Boltzmann method for simulation of binary mixtures
A new kinetic model for binary mixtures and its lattice Boltzmann (LB) discretization is formulated. In the hydrodynamic limit, the model recovers the Navier-Stokes and the Stefan-Maxwell binary diffusion equations, satisfies the indifferentiability principle, and is thermodynamically consistent. The present model is able to simulate mixtures with different Schmidt numbers and with a large molecular weight ratio of the components.

Abstract

A new kinetic model for binary mixtures and its lattice Boltzmann (LB) discretization is formulated. In the hydrodynamic limit, the model recovers the Navier-Stokes and the Stefan-Maxwell binary diffusion equations, satisfies the indifferentiability principle, and is thermodynamically consistent. The present model is able to simulate mixtures with different Schmidt numbers and with a large molecular weight ratio of the components.
