Laser-spark and pulsed nanosecond ignition for hydrocarbon fuels

Abstract

The project outlined in this white paper is an experiment designed to determine the differences andrelative effectiveness of laser spark ignition and pulsed nanosecond-duration discharge ignition inthe supersonic combustion of gaseous hydrogen fuels. The amount of energy deposited into theflow is kept constant between the two methods; and floor static pressure measurements, flowvisualizations and diode laser absorption measurements of temperature and water vapourconcentration at the combustor exit are used to compare the effectiveness of the two techniques.
