DC Corona Discharge in Air in a Point-to-Plane Configuration

Application ID: 100451

This tutorial model presents a study of a negative corona discharge in dry air at atmospheric pressure in a point-to-plane configuration. An elliptical electrode with millimeter dimensions creates a high intensity electric field where the corona discharge occurs. A ground plane is placed 10 cm away from the corona electrode. The voltage is varied between -5 to -50 kV. The creation and transport of charged species is solved self-consistently coupled with Poisson’s equation.

This model example illustrates applications of this type that would nominally be built using the following products:
