LATTICE-BOLTZMANN METHOD

The lattice-Boltzmann method has become a widely used tool for streamline-scale modeling in porous materials because of its easy implementation in complex geometries and its ability to capture inertial effects. We are working with a number of collaborators who have expertise in this area. The LBM simulations are being used to help validate the approximate solutions that are employed in network modeling.

The larger image on the right is a map of the magnitude of the velocity field in a small packed bed. Also shown is a tetrahedral pore from this packing (see network generation techniques) and the velocity field projected onto its face. Quantitative analysis of the flow profiles are being used to validate and improve network modeling algorithms. The LBM solution shown here was provided courtesy of Prof. Tony Ladd, University of Florida.
