An improved lattice Boltzmann model for simulations of single- and multiphase flows in porous media

Benjamin Ahrenholz & Benjamin Ahrenholz
During the last few years, the lattice Boltzmann method (LBM) has become a well established tool for simulating fluid flows [1,2], especially multi-phase flows in complex geometries. However, to the best of the authors’ knowledge, available multiphase models are only first order accurate in space due to shortcomings with respect to the accuracy of the multi-phase coupling terms in the vicinity of walls. We propose extensions for a multi-phase model discussed in [3] to obtain...
