OH and CH2O Laser-Induced Fluorescence Measurements for Hydrogen Flames and Methane, n-Butane, and Dimethyl Ether Weak Flames in a Micro Flow Reactor with a Controlled Temperature Profile

Laser-induced fluorescence (LIF) measurements were applied for the first time to a micro flow reactor with a controlled temperature profile to investigate general combustion and ignition characteristics of hydrogen (H2/O2/N2 mixture at O2/N2 = 1:9), methane, n-butane, and dimethyl ether (DME) (fuel/air mixtures). For the hydrogen case, overall flame responses of the H2/O2/N2 mixture against inlet flow velocity were investigated on the basis of...
