Chemiluminescence spectroscopy to explore the flame temperature

open access: yesNihon Kikai Gakkai ronbunshu, 2017
To explore the behavior of near-extinction flamelets in turbulent premixed flames, emission intensities of OH, CH and C2 radicals of hydrocarbon-air premixed flames have been examined using the newly developed emission spectroscopy system.
