초록

정상초음파의 영향을 받는 메탄-공기 예혼합화염의 주파수-당량비 상관도 분석을 위한 실험적 연구가 수행되었다. 고속카메라를 이용하여 예혼합화염의 전파영상을 획득하였으며, 영상 후처리를 통해 화염전파속도와 함께 화염의 전파거동을 면밀히 관찰하였다. 이론당량비 이하의 연료희박 당량비 구간에서 정상초음파가 개재할 때, 연소반응 촉진으로 인해 화염전파속도는 증가하였으나 화학반응강도가 포화상태에 이르는 당량비에서는 그 속도가 감소하였다.

An experimental study was performed for the analysis of frequency-equivalence ratio correlation in the methane-air premixed flame influenced by ultrasonic standing wave. Evolutionary features of the propagating flame were caught by high-speed camera, and the variation of flame-behavior including local velocities was investigated in detail using a post-processing analysis of the high-speed images. It was found that propagation-velocity augmentation of the methane-air premixed flame by the intervention of ultrasonic standing wave was made in leaner mixture, but the velocity diminished when the strength of chemical reaction was saturated around the slightly fuel-rich side of stoichiometry.
