Simulation of cohesive fine powders under plane shear
Three dimensional molecular dynamics simulation of cohesive dissipative powders under a plane shear is performed. By drawing the phase diagrams for several densities, we confirm the existence of various distinct steady phases, where some of them are realized by competition between the equilibrium phase transition and the dynamic instability caused by inelastic collisions. It is found that the s...
متن کاملSimulation of cohesive fine powders under a plane shear.
Three-dimensional molecular-dynamics simulations of cohesive dissipative powders under a plane shear are performed. We find the various phases depending on the dimensionless shear rate and the dissipation rate as well as the density. We also find that the shape of clusters depends on the initial condition of velocities of particles when the dissipation is large. Our simple stochastic model repr...

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Cohesive, frictional powders: contact models for tension
The contacts between cohesive, frictional particles with sizes in the range 0.1–10μm are the subject of this study. Discrete element model (DEM) simulations rely on realistic contact force models—however, too much details make both implementation and interpretation prohibitively difficult. A rather simple, objective contact model is presented, involving the physical properties of elastic–plasti...
متن کاملTheory of the Settling of Fine Particles.
in density due to particle content, the new elements which are continuously brought to the top of the cold wall are drawn from the top portion of the liquid and are of nearly uniform density. When A reaches its equilibrium depth, its downward flow is decelerated and it turns into the interior of the liquid, this motion being followed by the elements behind A. The equilibrium depth for A thus ac...
