Lattice gas model for transport and dispersion phenomena of air pollutants A. Salcido Instituto de Investigations Electricas, Division de Fuentes de Energia, Departamento de Sistemas de Combustion, Apdo.

This model uses cellular automata methods in order to define a non-reactive two-species gas mixture which evolves in a square two- dimensional lattice. -The particles of the system may interact with each other up to second nearest neighbors via dispersive collisions which satisfy the mass, momentum and energy conservation principles. A gravity like external force is also included in the model. The computer simulations made with this model show that the system behaves as expected in the cases of plume rise and dispersion phenomena; in particular, our simula- tions show th
