Transient approach to steady state of discharge phenomena in corona device

The discharge phenomena in corona device was simulated with a transient approach up to the dynamic steady state. The proposed transient approach requires neither Kaptsov's assumption nor roughness factor. As a simple numerical example, the corona discharge between two concentric cylindrical electrodes was analyzed for two different applied voltages in the one-dimensional model. The results were presented and compared with those of the conventional method. To our knowledge, this is the first work that attempts to simulate the corona discharge up to the steady state with a complete transient approach.
