Cellular Automata simulation of wave propagation in inhomogeneous medium
Lattice Gas Cellular Automata (LGCA) models are based on amicroscopic model of a physical process and can be considered as an adjunct to traditional numerical methods for spatial dynamics simulation. In this paper, the dependence of wave velocity propagation on the parameters of the simple LGCA models is experimentally investigated for a 2D lattice with four neighbors. A technique for evaluation of LGCA-model parameters through the physical velocity of the sound wave propagation in the medium is given. The sound wave propagation process in inhomogeneous media formed of two different materials (aluminum and ebonite) is simulated.
