Origins of Hydrodynamics for a Granular Gas
James W. Dufty, J. Javier Brey
The basis for a hydrodynamic description of granular gases is discussed for a low density gas of smooth, inelastic hard spheres. The more fundamental mesoscopic description is take…
Brownian Motion in a Granular Fluid
J. W. Dufty, J. J. Brey
The Fokker-Planck equation for a heavy particle in a granular fluid is derived from the Liouville equation. The host fluid is assumed to be in its homogeneous cooling state and all…
Electron Dynamics at a Positive Ion
James W. Dufty, Ilya V. Pogorelov, Bernard Talin +1
The dynamics of electrons in the presence of a positive ion is considered for conditions of weak electron-electron couping but strong electron-ion coupling. The equilibrium electro…
Inherent Rheology of a Granular Fluid in Uniform Shear Flow
A. Santos, V. Garzo, J. W. Dufty
In contrast to normal fluids, a granular fluid under shear supports a steady state with uniform temperature and density since the collisional cooling can compensate locally for vis…
Hydrodynamic equations for granular mixtures
V. Garzo, J. W. Dufty
Many features of granular media can be modeled by a fluid of hard spheres with inelastic collisions. Under rapid flow conditions, the macroscopic behavior of grains can be describe…
Kinetic Theory and Hydrodynamics for Rapid Granular Flow - A Perspective
James W. Dufty
These are notes prepared for presentation at the workshop "Challenges in Granular Matter" at the Abdus Salam Institute for Theoretical Physics, Trieste, August 2001. Revisions and…
