Since computer performance has drastically increased, numerical simulation is a powerful means for simulation of fluid flow. However, combustion simulation is still challenging and it is difficult to simulate combustion field with both turbulence and detailed chemistry, because it takes much time to solve 2D or 3D governing equations such as conservation equations of mass and momentum. Recently, Lattice Gas Automata (LGA) has been proposed as an alternative approach for simulating fluids. It describes the fluid at more microscopic level by assuming that it is composed by mesoscopic particles. The space and time are all discrete, and the physical quantities take only a finite set of values. Macroscopic quantities such as density and velocity are determined by the collective behavior of particles. The scheme of this discrete model is simple and easy for parallel computing. In this work, we simulate combustion filed by LGA, coupled with a Laminar Flamelet model to determine the temperature and concentration of the mixture by fast-chemistry assumption. Two particles of fuel and oxidizer are used for simulating diffusion combustion. We focus on the so-called counter flow diffusion flame. Some results including flow, temperature, and concentration fields are shown.
