– A non-perturbative analysis of the Bhatnagar-Gross-Krook (BGK) model kinetic equation for finite values of the Knudsen number is presented. This analysis indicates why discrete kinetic versions of the BGK equation, and notably the Lattice Boltzmann method, can provide semi-quantitative results also in the non-hydrodynamic, finite-Knudsen regime, up to Kn ∼ O(1). This may help the interpretation of recent Lattice Boltzmann simulations of microflows, which show satisfactory agreement with… CONTINUE READING
