Simulation of PD Optical Signal Mechanism Based on FCT Algorithm

The flux-corrected transport (FCT) algorithm is used to simulate the two-dimensional planar needle-plate structure of the positive streamer model and the partial discharge process of tip defects. The variations in electron density, net charge density and electric field during the movement of the pos...

description The flux-corrected transport (FCT) algorithm is used to simulate the two-dimensional planar needle-plate structure of the positive streamer model and the partial discharge process of tip defects. The variations in electron density, net charge density and electric field during the movement of the positive streamer are obtained. By deducing the relationship between photon flux and photoionization term, the photon distribution function is analyzed, and the variation law of the photon flux (the number density of photons generated per second) of the streamer moving in the air is obtained. The results show that the maximum luminous point concentrates on the fast-moving head of the positive streamer in the air. The photon flux (the number of photons produced per second) is approximately exponential with the distance from the cathode, with a maximum of approximately 1.4×1028 s-1·m-3.
