Abstract

A microgravity experimental study of vibrofluidized granular gas with intermediate number density is performed. Local velocity distributions are investigated, and are found to deviate measurably from a symmetric distribution for the velocity component in the direction of vibration due to the boundary heating mechanism. One generalized granular hydrodynamic theory (GSH) is used for a phenomenological model to describe this extended boundary effect by introducing additional variables to the two-peak distribution profile, which provides an account for the understanding of the bulk boundary effect.
