Pdf this document is the final report for afosr grant f49620 97 1 0172 lattice gas models of complex fluid hydrodynamics under the terms of this grant the center for computational science . This book addresses three important aspects of lattice gases first it shows how such simple idealised microscopic dynamics give rise to isotropic macroscopic hydrodynamics second it details how the simplicity of the lattice gas provides for equally simple models of fluid phase separation hydrodynamic interfaces and multiphase flow. A lattice gas model of microemulsions simulation of certain complex fluid problems such as multiphase flow through porous media and the interaction of phase transitions with hydrodynamics . A continuous velocity lattice gas model for fluid dynamics computations is constructed the model combines a stochastic propagation scheme with a multi particle collision rule that conserves mass momentum and energy it is demonstrated that the particle velocities have a maxwell boltzmann distribution at equilibrium. Lattice gas hydrodynamics the study of fluid dynamics by means of lattice gas models is today one of the most important applications of cellular automata our group originally contributed to the birth of this field today the cam 8 architecture provides perhaps the best computing platform for lattice gas investigations
