Ignition and Supersonic Burning of Air - Fuel Mixtures Initiated by Electrical Discharges

Abstract

This report results from a contract tasking Moscow State University as follows: The contractor will investigate the use of pulsed plasma jets and transversal pulsed-periodic discharges to ignite and efficiently combust hydrocarbon fuel/air mixtures in supersonic flows. Effects of pulse duration pulse power. electrode material and operating frequency will be determined for both propane/air and kerosene/air mixtures over equivalence rations from 0.3 to 1.0 at Mach 1.5, 2.0 and 3.0. Diagnostics will be used to determine the radiation spectra for the different discharges in the supersonic flow. Measurements of chemical radical and electron concentrations will also be made. Corresponding numerical simulations will be compared to the experimental data.
