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...

A new thermal entropic lattice Boltzmann model on the standard two-dimensional nine-velocity lattice is introduced for simulation of weakly compressible flows. The new model covers a wider range of flows than the standard isothermal model on the same lattice, and is computationally efficient and...
