- I133 Study on flame structure of co-axial jet flames in High-Temperature Oxygen Combustion conditions
抄録
OH-PLIF measurements and numerical simulations were conducted for co-axial laminar jet flame of CH_4/N_2 in high-temperature air (relevant to High-Temperature Air Combustion Technology: HiCOT) flow and that of CH_4/CO_2 in high-temperature O_2/CO_2 (High-Temperature Oxygen Combustion: HiTOx) flow. In both HiCOT and HiTOx conditions, two types of lifted flames were observed: one (Lifted Flame A) showed strong OH signal near the flame base at high CH_4 mole fraction of the fuel stream (X_<CH4>) and another (Lifted flame B) showed strong OH signal near the flame tip at low X_<CH4>. The present computations successfully reproduced these two types of lifted flames. In the computations, Lifted Flame A was formed near stoichiometric line while Lifted Flame B was formed in the far downstream region of stoichiometric line. Based on the classification using the flame temperature, Lifted Flame A was classified to a tnbranchial lifted flame and Lifted Flame B was classified to mild combustion.
