The utility of the lattice Boltzmann method for modeling
fluid flow in complex geometries like porous materials
is examined. After study of some simple test cases,
results from large scale simulations of fluid flow
through digitized Fontainbleau sandstone, generated by
x-ray microtomography, are presented. Reasonably good
agreement is found when compared to experimentally
determined values of permeability for similar rocks. We
also calculate relative permeability curves as a
function of fluid saturation and driving force. The
potential for modeling flows in other microstructures of
interest to concrete technology will be discussed.
