The lattice Bhatnagar-Gross-Krook (LBGK) approach (Bhatnagar et al., 1954) assumes the matrix [[OMEGA].sub.ij] to be a c-number 1/[tau].
We also use the lattice Bhatnagar-Gross-Krook (LBGK) approach.
We consider only the cases where the "microscopic" value of n (introduced inside LBGK via [[mu]]) is the same as the "macroscopic" n value obtained through the modified Darcy's law, up to an acceptable error.
