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 digitized 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,modification 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.
