This paper presents an investigation of powder dispersion based on a combined computational fluid dynamics (CFD) and discrete element method (DEM) approach. Agglomerates of different particle sizes… (More)

Dense medium cyclone (DMC) units are widely used to upgrade run-of-mine coal in the coal preparation industry. Their simple design belies the complex flow patterns that existing within each unit.… (More)

We make remarks on Fernández Guasti’s paper [J. Phys. A: Math. Gen. 39 (2006) 11825-11832] by pointing out some mistakes Fernández Guasti derived therein. PACS number: 45.20.Dd, 02.60.Cb, 45.05.+x… (More)

This paper presents a numerical study of the gas-powder flow in a typical Lapple cyclone. The gas flow is obtained by the use of the Reynolds stress model. The resulting pressure and flow fields are… (More)

In this work, a numerical study of the gas-solids flow in a 3D gas-fluidized bed with an immersed horizontal cylinder is performed using the combined computational fluid dynamics (CFD) and discrete… (More)

We obtain possibly valuable information about the phase diagram of rather dense composite particles at high fermion as well as boson number density but low temperature, which is not accessible to… (More)

Macroscopic derivation of the entrainment in a supersolid cylinder induced by a surface elastic wave (of small amplitude) propagating along the flexible interface is conducted by considering the… (More)

Glassy matter, when subjected to high shear rates exhibit shear thinning, that is, the viscosity diminishes with increasing shear rate. One possible outcome for the almost vanishing viscosity is… (More)
