Abstract: The characteristics of 13 bit multi-velocity lattice gas automata model have been analyzed. The statistical method of estimating parameters, such as permeability etc., in lattice gas automata model is discussed. Furthermore, the model has been used for investigating fluid flow through porous media such as coke and some simulating structures. It is shown that the knowledge about fluid flow through porous media can be acquired not only in detail but also from statistics parameters by using lattice gas automata model.It is valid to model fluid flow through porous media whose geometry boundary condition is so complex.
