荷电气-固两相流动与静电喷粉研究进展综述

A Review of Gas-electrostatic Charged Particles Two-phase Flow and Electrostatic Dusting

评述荷电气-固两相流动与静电喷粉研究现状．着重介绍颗粒的荷电机理，气-固两相流动研究的理论、实验，激光多普勒测速技术在气-固两相流动研究中的实验技术以及静电喷粉装置与沉积特性．最后提出目前静电喷粉技术有待研究的问题．

The present state-of-art of the research on the gas-charged particles two-phase flow is reviewed. Stresses are laid on the introduction of the mechanicsms of particles charge,the theory and experiment and the use of LDV ingas-particles two-phase flow as well as the deposition and design of electrostaticdust-sprayer. Finally, some problems in the application of electrostatic dustingtechnique are pointed out.
