Discharge effect on the negative temperature coefficient behaviour and multistage ignition in C₃H₈-air mixture

It has been first shown by modelling that the discharge does not suppress but stimulates the development and increases the intensity of cool flame. It sharply reduces the delay time of cool flame ignition (isothermal stage) by more than 2 orders of magnitude and diminishes the total induction time by more than 1 order of magnitude due to radicals resulting from dissociation of fuel and oxygen molecules by electron impact. Under the discharge...
