INTERFACIAL PHENOMENA IN BOLTZMANN CELLULAR-AUTOMATA

A two-dimensional two-colour, nonlinear, Galilean-invariant, Boltzmann cellular automaton is developed and used to study two-fluid hydrodynamics and to model fluid interfaces. The interfacial tension and interface width are flexibly controlled by the parameters defining collision rules for the colored particles. Results of studies of both the static and dynamical relaxation of the surface tension and wetting properties are presented.
