Initiation and propagation of laminar premixed cool flames

Cool flames, being essential features of chemical kinetics of large hydrocarbon fuels, are closely related to the negative temperature coefficient (NTC) phenomenon and engine knock. In this work, the coupling of cool flame chemistry and convective–diffusive transport is computationally and experimentally investigated. A 1-D planar premixed cool flame induced by a hot pocket is first simulated for DME/O2/N2 mixtures with detailed chemistry and...
