Effect of electrically driven particles on air flow in a rectangular duct

Abstract

Electric field strength Minimum electric field strength for sustained particle motion Minimum lift-off electric field strength Force Drag force Force due to the electric field Volumetric flow rate Length Length of the duct where the steady state condition can be maintained Slope Number of particles per unit volume of the material Charge acquired by a particle Reynolds number based on the duct hydraulic diameter and the air bulk velocity Reynolds number based on the partcle diameter and the relative air to particle velocity

Quenching of particle-gas combustible mixtures using the electric particulate suspension (EPS) method

“…The parameters, , f α , and γ , are suggested to account for particle history effects, randomization as a result of collisions, irregular bounces, and particle rotation. Sarhan (1989) continued the application of EPS to the pneumatic transport of solids. An experimental investigation was carried out using an electric field to assist particle lift in a rectangular duct.…”
