Multicomponent Lattice Boltzmann Simulations of Gas Transport in a Coal Reservoir with Dynamic Adsorption

Figure 2

Simulation results of porous flow between plates. (a) The velocity profiles of a single-component fluid flow without mass transfer, ignoring the nonlinear drag force term. Note that velocity was normalized by the maximum velocity at the centerline of the channel . (b) The relationship between the concentration and the adsorbed amount of coupled flow with both fluid flow and gas diffusion. The results (symbols) are in good agreement with the analytical solution (lines).
