Lattice Gas Automata (LGA) is an alternative approach for simulating fluids. The scheme of this discrete model is simple and easy for parallel computing. In this work, we simulate combustion filed by this LGA model. Two particles of reactant and product are used, which have properties of the unburned and burned gases. The model includes convection, diffusion, and reaction. The degree of reaction is expressed with reaction probability depending on the local temperature. We focus on the counter flow premixed flames. The flow, temperature, and concentration fields are determined by collective behavior of particles. It is concluded that combustion field can be simulated by this two component LGA model.
