The dependence of NTC behavior on the equivalence ratio and nitrogen fraction in cool flame region

Using propane (which issues a cool flame at low temperature oxidation) as the archetype of the higher alkanes, comprehensive computational research, with detailed mechanisms and theoretical analysis, was implemented to investigate the controlling points of the cool flame region and the negative temperature coefficient (NTC) behavior. It found that the temperatures of the two turnover points steadily decreased with the increase of equivalence...
