Simulation of cohesive fine powders under plane shear


We perform three dimensional molecular dynamics simulation of cohesive dissipative particles under a plane shear. From the simulations, we find the existence of various types of distinct steady phases, one of which is realized by competition of the equilibrium phase transition and the dynamic instability caused from inelastic collision. Our analysis suggests that the classical nucleation theory is satisfied even in our system. We also found that the tail of velocity distribution function deviates from the Gaussian in the interfaces between dense cluster and dilute gas regions of the coexistence phase.
