An experimental study on the effect of pressure and strain rate on CH chemiluminescence of premixed fuel-lean methane/air flames
TLDR
In this paper, the authors investigated the possibility of using chemiluminescence as an active feedback control parameter to deduce the equivalence ratio, and therefore NO x production and combustion stability, for premixed flames at high pressure.About:
