Effect of burnt gas mixing on the extinction of interacting flames premixed

기연가스의 혼합이 상호작용을 하는 예혼합화염의 소화특성에 미치는 영향에 관한 연구

The effects of burnt gas mixing, which can be caused by turbulent eddy mixing, on the interaction and extinction characteristics of premixed flames are analyzed using large activation energy asymptotics adopting counterflow as a model problem. The results show that the burnt gas mixing, preferential diffusion and heat loss affect the fuel consumption rate, flame temperature and the oxidizer concentration at the flame which influence the flame behavior and the extinction characteristics.
