Effect of fuel type on equivalence ratio measurements using chemiluminescence in premixed flames
M. Orain,Yannis Hardalupas +1 more
TL;DR: In this article, local temporally resolved measurements of chemiluminescent intensity from OH ∗, CH ∗ and C ∗ 2 radicals were obtained in premixed counterflow flames operating with propane and prevaporised fuels (isooctane, ethanol and methanol), for different equivalence ratios and strain rates.
