Towards granular hydrodynamics in two-dimensions,
E. L. Grossman, T. Zhou, and E. Ben-Naim
We study steady-state properties of inelastic gases in two-dimensions
in the presence of an energy source. We generalize previous
hydrodynamic treatments to situations where high and low density
regions coexist. The theoretical predictions compare well with
numerical simulations in the nearly elastic limit. It is also seen
that the system can achieve a nonequilibrium steady-state with
asymmetric velocity distributions, and we
discuss the conditions under which such situations occur.
