摘要

A numerical model is developed and the calculation results of plasma dynamics in gaseous channels of streamers propagating in hydrocarbon liquids are presented. It is shown that, due to Joule heating leading to a reduction of the gas density, the local electric field, governed by the ionization-recombination balance of charged species, decreases along the channel. As a result, the mean electric field in long gaseous channels decreases with the growth of channel length. Correspondingly, the calculated length of streamer propagation (stopping length) increases with applied voltage faster than linearly, in accordance with experimental data. Calculated values of the mean electric field in long gaseous channels agree with those obtained in experiments on streamer propagation in long gaps.
