Autoignited laminar lifted flames of propene in heated coflow jets: Dependence on ignition delay time

This paper presents an experimental study of the characteristics of laminar lifted flames of non-premixed propene in coflow jets of air heated at initial temperatures ranging from 800 to 1000 K, under atmospheric pressure. The results showed that the jet-velocity-dependent flame behavior of propene agrees well with that of the methane, ethylene, and ethane cases in the earlier C1–C4 studies: (1) the nonautoignited nozzle-attached flame (NA-NA),...
