What Can the Electric Discharge Module Do?
The Electric Discharge Module provides a unique environment for simulation of electric discharges. The module is a powerful tool for detailed analysis of low-temperature and high-temperature gas discharges as well as charge transport in liquid and solid dielectrics. With this module you can run static and transient simulations in an easy-to-use user interface.
The available physics interfaces cover the following types of electric discharge simulations:
•
Arc discharges
•
Corona discharges
•
Dielectric barrier discharges
•
Electrostatic discharges
•
Streamer discharges
In addition to the standard results and visualization functionality, the module supports direct computation of lumped parameters such as discharge current.
Selected material data are provided with the module.
For detailed information about Materials including the Electric Discharge Material Library, see the COMSOL Multiphysics Reference Manual.
Like all COMSOL modules, there is a library of ready-to-run models that make it quicker and easier to analyze discipline-specific problems. In addition, any model you develop is described in terms of the underlying partial differential equations, offering a unique way to see the underlying physical laws of a simulation.
The Electric Discharge interfaces are fully multiphysics enabled — couple them to any other physics interface in COMSOL Multiphysics or other modules. The Electric Discharge Module contains predefined multiphysics interfaces to facilitate easy setup of models with the most commonly occurring couplings. For example, the Arc Discharge multiphysics interface combines all features from the Magnetic and Electric Fields interface in the stationary and time-dependent formulations with the Heat Transfer interface and Laminar Flow interface to model the dynamics of electric arc.
The Electric Discharge Module also provides interfaces for modeling electrical circuits.
