Conference Report: NIST TUTORIAL/WORKSHOP ON LATTICE GAS AND BOLTZMANN METHODS Gaithersburg, MD August 21-23, 1995

The flow of fluids in complex geometries like porous media [1] plays an important role in a wide variety of technological and environmental processes including chromotography, oil recovery, the degradation of building materials and the spread of hazardous wastes in soils. The complexity of such flow processes makes their theoretical and experimental study a great challenge. Recent developments in cellular automata methods such as lattice gas and lattice Boltzmann allow for the accurate solution of the Navier-Stokes equation for multi-phase and multi-component fluid flow [2], [3], [4]. The advantage of these methods over traditional approaches, such as finite difference and finite element methods, is that they naturally accomodate complex [J. Res. Natl. Inst. Stand. Technol. 101, 705 (1996)]
