摘要/Abstract

摘要： 该文采用颗粒群模型研究荷电固粒相在绕圆柱无穷远均匀气相流场和统圆柱导体无穷远均匀静电场中的定常运动,得到的最重要的结论是:荷电对固相运动的影响随固粒粒径的减小而降低.

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
