Combustion Flame Diagnostics Using Laser-Induced Fluorescence

레이저 유도 형광법에 의한 연소화염 진단기법 연구

A laser system and signal aquisition system to use a laser-induced fluorescence technique were arranged to measure NO concentration. To identify the NO fluorescence signal, verification of the fluorescence was performed through use of comparison of the signals taken both in a undoped and doped calibration flames. Finally, the spatial NO number densities in partially premixed flames were found as a function of fuel-tube equivalence ratio(${\phi}_c$) and overall equivalence ratio(${\phi}_o$).
