  • Title: Homogeneous steady state of a confined granular gas.
    Author: Brey JJ, García de Soria MI, Maynar P, Buzón V.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2013 Dec; 88(6):062205. PubMed ID: 24483434.
    Abstract:
    The nonequilibrium statistical mechanics and kinetic theory for a model of a confined quasi-two-dimensional gas of inelastic hard spheres is presented. The dynamics of the particles includes an effective mechanism to transfer the energy injected in the vertical direction to the horizontal degrees of freedom. The Enskog approximation is formulated and used as the basis to investigate the temperature and the distribution function of the steady state eventually reached by the system. An exact scaling of the distribution function of the system having implications on the form of its moments is pointed out. The theoretical predictions are compared with numerical results obtained by a particle simulation method, and a good agreement is found.
