Computation of Electric Wind Parameters in Direct Current Corona Field

摘要

Direct current corona discharge is often used in many industry applications to charge small particles and liquid droplets and to control trajectories of their motion. Movement of charges in outer zone of the discharge is complicated due to drag of neutral air molecules. This is the reason of electrohydrodynamic flow rise named as electric wind. Electric wind phenomenon can be used for heat and mass enhancement, in ionic air cleaners etc. [1]. During the last decades many results of experimental and theoretical research are published [2]. Because of high voltage conditions in the discharge gap authors use for experimental research laser-Doppler anemometers, particle image velocimetry systems or hot-wire anemometers [3].
