摘要

This paper compares numerical simulations with experiments to describe the underlying mechanisms responsible for the voltage-current characteristic (VCC) response of a capillary-fed methane diffusion flame in an electric field. The numerical simulations, which include both combustion and electric phenomena, show good agreement with previously published experimental results, though computed flame temperatures were higher than those experimentally measured. Sub-saturated, saturated and supersaturated ion current regions are shown in the range of applied potentials: 0-2.5 1
