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 …
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 …
In general, mass transport and diffusion process involve complex geometries and complicated non-linear interactions between components. Analytical models are usually inappropriate and experiments are not always possible. Numerical simulations are …
The simulation of the multicomponent viscous fingering instability in the case of miscible fluids at high Schmidt number is investigated. This instability, firstly highlighted by Saffman and Taylor, occurs when a fluid of low viscosity moves into a …
