Abstract

The cellular automaton method, which can generate the Navier-Stokes equation, is utilized for simulating fluid motion numerically. This method has the advantage of allowing examination of the statistical property involved in the macroscopic variables, since the elementary process is described as a stochastic process. The present paper demonstrates that an automaton solution of Poiseuille flow results in turbulent behavior with a Reynolds number of 3200. After careful review of the calculated intensity of turbulence and correlation function of this solution, it may be concluded that this method serves as a reasonable alternative to the Large-Eddy-Simulation (LES) and k-ε methods for examining turbulent flow.
