GAS-DYNAMICS OF CELLULAR-AUTOMATA (REVIEW)

The goal of the review is to acquaint experts in combustion and explos ion with the method of cellular automata, also called the lattice-gas method, a comparatively new approach to modeling of gas-dynamic proces ses. The motion of a continuous medium is modeled directly by calculat ing the evolution of a special microworld of particles, which move in a fixed two- or three-dimensional lattice and collide with each other at the lattice sites. In essence, what is involved is the most simplif ied version of molecular dynamics. Examples are given of application t o various problems, including calculation of reacting flows, unstable problems, and flows in a complex geometry. Possible applications of th e method in the physics of combustion and explosion are discussed.
