A Lattice Gas Model for Twodimensional Boussinesq Convection
Abstract
In this paper, we present a 2-D model for simulating the convection of an incompressible fluid between two walls of different temperatures. In particular, a bidimensional cellular automaton (CA) was developed to study the evolution of a discrete particle system, which represents a modified Frisch-Hasslacher-Pomeau (FHP) lattice gas. The derivation of the model equations and some relevant diagnostics, such as the Rayleigh, Prandtl and Nusselt numbers, are briefly outlined. The diagnostics computed for test runs indicate the consistency of the model as well as the preliminary simulation performed with a CA.
