Limiting particle charge for electrification in a corona discharge field

  • 21 Accesses

Abstract

An experimental study is performed of electrification of objects from a dielectric fluid within a corona discharge field. Use of jet monodispersion permits comparison of data on charging of a cylindrical surface and spherical particles, elimination of the effect of dynamic factors, refinement of the electrification mechanism and limiting charge value. It is shown that aside from other factors, the limiting charge is defined by the cross sectional area of the electrified object, and is approximately 30% less than previously accepted values.
