Rheology of magnetofluidized fine powders
(2010)
Usually a bed of solid particles °uidized by a gas is inherently unstable. Gas bubbles are rapidly formed at the onset of °uidization, which hinders the e±ciency of gas-solid contact. In the case of magnetizable particles, ...

Numerical simulation of EHD flows using Discontinuous Galerkin Finite Element methods
(Elsevier, 2013)
The aim of this paper is to explore the capability of Discontinuous Galerkin Finite Element methods to solve numerically the charge transport equation in EHD convective flows, in both strong and weak injection regimes. ...

Magnetic field induced inversion in the effect of particle size on powder cohesiveness
(AIP Publishing, 2010-07)
Experimental measurements are reported on the tensile yield stress of magnetofluidized beds of fine magnetic powders operated in the cross-flow configuration. In the absence of externally applied magnetic field the yield ...

Fluid to solid transition in magnetofluidized beds of fine powders
(AIP Publishing, 2010)
Experimental observations on the fluid to solid transition in beds of magnetized fine particles fluidized by gas are reported for different particle sizes dp. Contrarily to stability analysis prediction, the fluidized ...

Numerical Modelling of Electrical Discharges
(2014)
The problem of the propagation of an electrical discharge between a spherical electrode and a plane has been solved by means of finite element methods (FEM) using a fluid approximation and assuming weak ionization and ...

Electric charge limits on settled powders
(AIP Publishing, 2016)
In flows of dry particulate systems, electric charge is generated on particle surfaces by their collision with walls and with other particles. Charge build-up on single particles can yield local charge values high enough ...
