과농-희박 예혼합화염의 상호작용에 관한 연구
On the interaction of rich-lean premixed flames
- 발행 : 1987.11.01
초록
본 연구에서는 과농-희박 연료장에서 화염들의 상호작용에 관하여 이론적 해 석 및 실험적 검증을 통해 연구하였고, 이 중 특히 두 개의 예혼합화염 사이에 확산화 염이 형성되어 세 개의 화염이 존재하는 영역을 고찰하였다.
Existence of triple flames in a lean-rich concentration field is studied both experimentally and theoretically using large activation energy asymptotic technique adopting counterflow system as a model problem. Experiment shows that in triplet system of a lean and a rich premixed flame separated by a diffusion flame, either lean or rich premixed flame merges with diffusion flame as stretch is increased, such that transition boundary between 3-flame and 2-flame exists. The region in which 3-flame can exist forms an island within rich-lean concentration fields for large stretch, where as it is extends to the line of (.OMEGA.
