Due to its inherent mesoscopic character and ease of implementation and parallelisation, the lattice Boltzmann method (LBM) has become a popular model for simulations of soft matter systems.
Earlier, a multi relaxation time lattice Boltzmann model for amphiphilic fluid mixtures was presented. This model allows to resolve some of the problems existing in the broadly used single relaxation time schemes. The code allows the simulation of binary and ternary multicomponent systems, containing (im)miscible and optionally amphiphilic fluid species.
Results of the investigation of applicability of the model to simulate fluid mixtures in porous media are presented. Interesting physical properties include diffusivity and relative permeabilities.
