Abstract

A quasielastic one-dimensional granular gas of pointlike particles was analyzed between two thermalizing walls in the absence of gravity. The two control parameters namely the total inelasticity parameter and externally imposed temperature gradient were discussed. The comparison between integration of the Boltzmann equation using the direct-simulation Monte Carlo method and results stemming from microscopic Newtonian molecular dynamics establishes the non-Gaussian feature of the distribution function in the fluidized state.
