Abstract

The results of laboratory-scale experiments on plasma-induced hydrogen and ethylene ignition and flameholding by means of near-surface electrical discharge are presented. The ignition and flameholding were demonstrated for direct fuel injection into the supersonic air. A two-zone model of plasma-induced ignition is proposed to explain the experimental data. Numerical simulations were performed to confirm the two-zone model of plasma-assisted ignition.
