Abstract
This paper describes a simulation of diffusion phenomena by Cellular Automata. Cellular Automata are known as a class of modeling technique originally developed in the field of information engineering, in which the flow of information can be modeled systematically. In the application of Cellular Automata in other engineering field, local neighbor rules and transition rules are introduced instead of the governing equation, and the state variables defined on the simulation field are evaluated on each time step by these rules. In the present application, the degree of concentration is represented by the number of particles set on the field. All the parameters treated in this procedure are discrete ones.
