Mesoscale Modeling: Beyond Local Equilibrium Assumption for Multiphase Flow
Wei Wang,Yanpei Chen +1 more
TL;DR: In particular, the mesoscale structure in terms of bubbles or clusters, which can be characterized by nonequilibrium features, is the critical factor for predicting the dynamic, none-ilibrium phenomena in circulating fluidized beds even with fine-grid resolution as discussed by the authors.

Hydrodynamics of granular gases with a two-peak distribution.
TL;DR: G granular hydrodynamics is generalized by introducing two additional variables, with one accounting for the distance between the two peaks and a second for the difference between the average velocities along different directions, yielding results that agree with experiments and simulations.
Asymmetric local velocity distribution in a driven granular gas
TL;DR: In this paper, the authors investigate the local feature of driven granular gases in event-driven molecular dynamic simulation, in order to achieve spatial profiles of local velocity distribution and granular temperature, and the local state with various coefficients of restitution.

Asymmetric velocity distribution in boundary-heating granular gas and a hydrodynamic description
Yanpei Chen,Meiying Hou,Pierre Evesque,Yimin Jiang,Mario Liu +4 more
- 18 Jun 2013
TL;DR: In this paper, a microgravity experimental study of vibrofluidized granular gas with intermediate number density is performed, and 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.
The anisotropy of free path in a vibro-fluidized granular gas
TL;DR: In this article, the free path of a 2D inelastic granular gas confined in a rectangular box is investigated by 2D event-driven molecular simulation, and the probability distribution of angle between the relative velocity and the unit vector joined two particle centers deviates from the distribution of two random vectors.
