Lattice Boltzmann model for miscible mixtures: application to the viscous fingering instability

In the first part of the presentation, we introduce a lattice Boltzmann model for miscible gases. In this model, the standard lattice Boltzmann algorithm is employed for each species composing the mixture. First, the diffusion between species is …

Simulation of Viscous Fingering Instability by the Lattice Boltzmann Method

The viscous fingering instability is successfully simulated within a lattice Boltzmann framework. Each species of the mixture is governed by its own kinetic equation and a force takes into account the diffusion between species. The influence of the …
