Improvement of Corona Discharge Model and Its Application on Simulating Corona Discharge in the Presence of Wind

Figure 2

Contours of the number density of small positive corona ions (per cubic meter) produced by the corona from a 60 m tall grounded rod tip computed with the 2D model in the Cartesian coordinate system (a) and contour plots adapted from Figure  14 in Becerra [17] (b). The result corresponds to the background electric field reaches at 20 kV m⁻¹ produced by thunderstorm.
