Abstract
We use a cellular-automata (CA) method to determine the frequency-depe ndent permeability k(omega) of a channel and a disordered porous mediu m. The CA results for the channel flow agree completely with the analy tical solution of the problem. For flow in a porous medium, we calcula te k(omega) over a wide range of the frequencies omega and for several values of the porosity. Our CA results for disordered porous media su pport the relation k(omega)/k0 = f(omega/omega(c)) where k0 is the sta tic permeability of the medium, omega(c) is a characteristic frequency , and f(x) is a universal function, proposed previously, based on expe rimental data.
