文摘

Particle elutriation is for the first time studied by CFD-DEM modeling. Electrostatic effects on particle elutriation is studied by CFD-DEM modeling. Simulated results showed that static electricity suppressed particle elutriation. Effect mechanism of static electricity is a kind of multifactor effect mechanism. In the multifactor effect mechanism, agglomerates is the most predominant.
