PARTICLE METHODS ONLY SUiTED FOR MODELING ADVECTIVE TRANSPORT ? SOME COUNTER - EXAMPLES

"Particle models" is a generic term used for a broad class of simulation models in which the discrete representation of physical phenomena involves the use of interacting particles. Since this technique was first applied by Ahlstrom et al. (1977) to numerical studies of groundwater hydrology, many other researchers have used it with success. Unlike the conventional Eulerian methods, particle tracking methods (TMs) have no grid Peclet number problems or grid orientation effects, and are traditionally considered as well suited for advection dominated simulations.
