dc.description.abstract | The inhomogeneous cooling state describing the hydrodynamic behavior of a freely evolving granular gas
strongly confined between two parallel plates is studied, using a Boltzmann kinetic equation derived recently.
By extending the idea of the homogeneous cooling state, we propose a scaling distribution in which all the time
dependence occurs through the granular temperature of the system, while there is a dependence on the distance to
the confining walls through the density. It is obtained that the velocity distribution is not isotropic, and it has two
different granular temperature parameters associated to the motion perpendicular and parallel to the confining
plates, respectively, although their cooling rates are the same. Moreover, when approaching the inhomogeneous
cooling state, energy is sometimes transferred from degrees of freedom with lower granular temperature to those
with a higher one, contrary to what happens in molecular systems. The cooling rate and the two partial granular
temperatures are calculated by means of a Gaussian approximation. The theoretical predictions are compared
with molecular dynamics simulation results and a good agreement is found. | es |
