Abstract

First evaluations of a lattice gas approach to air pollution modelling A. Salcido ABSTRACT Application of lattice gas techniques for the computer simulation of transport and dispersion phenomena of air pollutants has been proposed very recently. However, in order to be useful as a reasonable approach to air pollution modelling, the transport and diffusion properties of lattice gas models must be characterized for equilibrium and non-equilibrium situations similar to the atmospheric ones. In this work, three problems have been considered for a square two-dimensional (2D) lattice gas model with interactions up to second nearest neighbors satisfying the mass, momentum and energy conservation principles: a theoretical discussion of the equilibrium thermodynamic properties of the gas model, the characterization of its equilibrium diffusion properties, and the agreement of the gas model flow behavior with the Navier-Stokes predictions under steady and non-steady flow conditions.
