ResumoA method is described for measuring low-energy ignition of combustable mixtures using nanosecond and picosecond laser-induced breakdown. Ignition studies are reported for homogeneous H2/air mixtures. The extent of flame inhibition in H2/air was investigated as a function of CO2 concentration. Our electrodeless spark ignition results are compared with earlier work using electric discharge ignition. A simple model for flame ignition is advanced, based on the temporal and energy density characteristics of the source energy. Implications of laser-induced spark ignition in homogeneous fuel mixtures to the molecular dynamics of flame propagation are discussed.
