Isometric Collision Rules for the Four-Dimensional FCHC Lattice Gas

Collision rules are present ed for th e four-dimensional facecentered-hypercubic-lattice (FCHC) . The velocity set after collision is deduced from th e velocity set be fore collision by an isometry, chosen so as to preserve th e momentum and minimiz e the viscosity. A detailed implementation recipe is given. Th e shea r viscosity is camputed; th e result shows that essentially all memory of t h...

Lattice-Gas Dynamics, Volume I Viscous Fluids

Lattice-Gas Dynamics Volume I Viscous Fluids The theory and computation of lattice gas dynamics for viscous fluid hydrodynamics is presented. Theoretical analysis of these exactly conserved, discrete models is done using the Boltzmann approximation, a mean-field theoretical treatment. Theoretical results are then compared to numerical data arrived at by exactly computed simulations of simple la...

Aging in lattice-gas models with constrained dynamics

We investigate the aging behavior of lattice-gas models with constrained dynamics in which particle exchange with a reservoir is allowed. Such models provide a particularly simple interpretation of aging phenomena as a slow approach to criticality. They appear as the simplest three dimensional models exhibiting a glassy behavior similar to that of mean field (low temperature mode-coupling) mode...
