Corona Discharge in Point-to-Plane Electrodes
Application ID: 148121
This model analyzes negative corona formation in a point-to-plane configuration driven by high applied voltages. The resulting I–V characteristics align well with experimental observations documented in the literature. The goal here is to capture the steady electrical characteristics without modeling the rapid Trichel pulse sequence. To achieve this, a limited and fixed density of preexisting charge carriers is introduced near the electrodes. For time-resolved modeling of Trichel pulses, see the trichel_pulses model available in the application library.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
