Abstract
We study steady-state properties of inelastic gases in two dimensions in the presence of an energy source. We generalize previous hydrodynam ic 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 achie ve a nonequilibrium steady state with asymmetric velocity distribution s, and we discuss the conditions under which such situations occur.
