Abstract

Charged clouds, generated in industrial processes, can lead to large values of space potential and electric field inside a vessel. Isolated masses of airborne liquid within can carry induced charge to the wall resulting in electrostatic discharges. Critical values of space potential can be found using a relationship between the jet safety factor and the material hazard coefficient. A computer package is described which allows complex space potential profiles and electric fields to be modelled for a prescribed space charge density. This allows the central space potential, a key indicator of electrostatic risk, to be evaluated. Examples are presented of two recent hazard investigations made by Wolfson Electrostatics.
