I’m new to LBM and Palabos and I’m facing the problem of mass transport in porous media. I already solved the velocity field for a single component fluid. Now, I would like to simulate the behaviour of air (N2 and O2 solution) within the material and, reached the steady state, I would like to compute the concentration field inside the material after applying different boundary conditions for each species. Can I use the Shan and Chen model to solve the mass transport problem?
I have seen here an example of a simple diffusion process using the Shan - Chen model simply obtained modifying the R-T instability code. It seems it works eventhough I’m wondering if it is the right way to preceede. Does anybody had the same problem as me?
Thank to you all.
