Effects of an electrostatic field in pneumatic conveying of granular materials through inclined and vertical pipes

Effects of external electric field on bubble and charged particle hydrodynamics in a gas–solid fluidized bed

“…Due to the frequent collision and friction between particles and the wall, the gas phase, as well as other particles, the electrostatic charges are easily generated. This phenomenon of charge accumulation on the particles is usually unavoidable and undesirable in most dry particulate systems [1], which can lead to sparks, explosions, particle sheeting, agglomeration and even defluidization. Besides, the electrostatic charge generation will also affect the bubble dynamic behavior (such as size, shape) and the particle elutriation rates [2,3].…”

Discrete element simulation for the evaluation of solid mixing in an industrial blender

“…This methodology is referred to as the DEM-CFD method [14]. The DEM-CFD method has been used to model a variety of dense gas-solid flows such as a bubbling fluidized bed [15][16][17][18][19]and pneumatic conveying [20,21]. Very recently, new Lagrangian-Lagrangian approaches have been developed to simulate solid-liquid flows involving free surfaces, where the DEM is coupled with a Lagrangian CFD approach such as the smoothed particle hydrodynamics (SPH) method [22] or the moving-particle semi-implicit (MPS) method [23].…”

Gelation of Magnetic Nanoparticles

“…The molecular dynamics approach to modeling of particulate systems, otherwise known as the Discrete Element Method (DEM), has been applied extensively for studies of flow behaviors in various types of granular and multiphase systems (Lim et al, 2006a(Lim et al, , 2006bLim and Wang, 2006;Lim et al, 2007;Lim, 2007Lim, , 2008Lim, , 2009Lim, , 2010aLim, , 2010bLim et al, 2011). For a comprehensive review, the interested reader is referred to a recent review article by Zhu et al (2008).…”
