Long time simulations of granular hydrodynamics : instabilities and attractors
Srikant Marakani, Gene F. Mazenko
Using a hydrodyamic model of granular flows, we present very long time simulations of a granular fluid in two dimensions without gravity and with periodic boundary conditions in a…
Granular clustering in a hydrodynamic simulation
Scott A. Hill, Gene F. Mazenko
We examine the hydrodynamics of a granular gas using numerical simulation. We demonstrate the appearance of shearing and clustering instabilities predicted by linear stability anal…
Perturbation Expansion in Phase Ordering Kinetics
Gene F. Mazenko
A consistent perturbation theory expansion is presented for phase ordering kinetics in the case of a nonconserved scalar order parameter. At lowest order in this formal expansion o…
Ordering kinetics of defect structures
Gene F. Mazenko, Robert A. Wickham
We show how the continuity equations expressing conservation of topological point or string defect charge can be used to determine the order-parameter correlation function for the…
