Abstract: The lattice Boltzmann method is a promising
approach for modeling single and multicomponent fluid
flow in complex geometries like porous materials.Here,
we review some of our previous work and discuss some
recent developments concerning fluid f low in multiple
pore size materials.After presenting some simple test cases
to validate the model,results from large scale simulations
of single and multi-component fluid f low through digi-
tized Fontainebleau sandstone,generated by X-Ray
microtomography,are given.Reasonably good agreement
was found when compared to experimentally determined
values of permeability for similar rocks.Finally,modifica-
tion of the lattice Boltzmann equations,to describe flow
in microporous materials,is described.The potential for
modeling flows in other microstructures of interest to
concrete technology will be discussed.
