Numerical analysis of transit conduction current in an insulating liquid with added ionic electrolyte

Abstract

SUMMARYWe simulated the phenomena of transit conduction in an insulating liquid with added ionic molecules such as surfactant, by using the charge-injection model with dissociation-recombination. When the parameters of C i (density of injected charge) and C 0 (density of created charge in the liquid) are C i > C 0 in this simulation, the waveform of current density showed an injection type with a peak, and when C i < C 0 , it showed a dissociation-recombination type. A decreasing characteristic appeared in the low electric field, maximum one in the middle field, and saturating one in the high field.
