What is The simulation of powders with liquid bridges in a 2D vibrated bed about?

The discrete element method is employed to study the convection cells of wet glass beads in a two-dimensional vibrated granular bed. Three types of viscous uids with di erent values of viscosity are used in this work. A simpliÿed model of dynamic bridge strength based on the superposition of lubrication and circular approximation is used in the simulation model. The owÿelds of wet particles, the depth proÿles of solid fraction and granular temperature as functions of the altitude are investigated. The mechanism of energy dissipation due to friction, inelasticity, viscous resistance and liquid bridge bond rupture are also discussed in detail. For wet granular materials, the liquid bridge force due to surface tension and viscosity interacts with frictional force mutually to determine the strength of the convection ow rate. The energy dissipation is mainly associated with the viscous force, the interparticle friction and the inelasticity of collision, rather than with the capillary force of liquid bridge. The energy dissipation increases monotonously with the increase of the dimensionless interstitial liquid volume, and the distributions of the energy dissipation are strongly in uence
