Abstract: Adopting the particle-cloud model, this paper discusses the steady motion of a charged solid-phase in a gas-phase flow-field around a cylinder with a uniform flow at infinitude and in an electrostatic field around the cylindrical conductor with a uniform electric field intensity at infinitude. The most important result is that the smaller the solid-phase particle diameter the weaker the effect of charging on the solid-phase motion.

Key words: gas-solid flow, charging, around a cylinder
