Abstract
Lattice Gas Automata (LGA) and the Lattice Boltzmann method (LBM) are
specific Cellular Automata (CA) that can be considered as simplified discrete
particle models capable of modeling fluid flow. LGA and LBM inherit the
intrinsic parallelism of CA. We discuss our distributed particle simulation of
flow, based on a parallel LBM. Efficient parallel execution is possible, provided
that (dynamic) load balancing techniques are applied. Next, we present a number
of case studies of flow in complex geometries, i.e. flow in porous media and in
static mixer reactors.
1 Introduction
Cellular Automata (CA) are discrete, decentralized, and spatially extended
systems consisting of large numbers of simple identical components with local
connectivity. The rational of cellular automata is not to try to describe
