A Study on the Laminar Burning Velocity Using an Angle Method and Annular Diverging Channel Combustor and Characteristics Of Chemiluminescence

각도법과 동심형 확장 채널 연소기를 이용한 연소속도 측정 및 화염 발광 특성에 관한 연구

In this study, the laminar burning velocities of SNG fuel were studied using both experimental measurements and kinetic simulations. They were measured using the angle method of Bunsen flame configuration and the annular diverging channel combustor. And they were also numerically calculated by CHEMKIN Package with GRI 3.0 mechanisms. Spectrometer was used for characteristics of flame chemiluminescence of SNG fuels. From results of this work, first, we found that according to adding $H_2$ contents in the fuels the laminar burning velocities of SNG fuels were increased. And second, we also discovered existence of OH*, CH*, $C_2*$, HCO*, $CH_2*$ radicals and their correlation.
