Abstract
Numerical simulation model of separating discharge is proposed in order to simulate the separating discharge patterns generated on the back-side of the sheet, which is separated from the grounded metal. As Poisson's equation is solved taking into consideration separating discharge, surface discharge and movement of the sheet, discharge patterns on the backside of the sheet are simulated. The number of the discharge patterns, discharge gap and potential distribution on the back-side of the sheet after separation are calculated and compared with the experimental results. These simulation results show good agreement with the experimental results. These comparisons confirm that this model can be used for the study of preventing separating discharge and reducing the harmful effect of the separating discharge.
