Statistical properties of granular gas under microgravity --- one dimensional inelastic hard rod system
POSTER
Abstract
We have studied numerically statistical properties of granular gas in a one-dimensional inelastic (viscoelastic) hard rod model under microgravity, which is designed to the mimic experimental granular vibrated beds by introducing a velocity- dependent restitution coefficient. Our systematic simulations show that various macroscopic properties of this model are quantitatively different from a linear combination of the previous simulations based on the constant restitution coefficient. The present results are significantly important to study a vibration response and dynamics of granular gas especially in microgravity experiment.
