对声波扰动下V 形预混火焰的锋面皱褶进行了动态分析,建立了声波扰动V形预混火焰的实验台,通过精细热电偶探测火焰锋面皱褶的变化,测量了不同声波扰动频率下的V形预混火焰的锋面皱褶.实验结果与分析结果一致,表明V 形预混火焰锋面皱褶的频率与声波扰动频率相同,火焰锋面皱褶的幅值随着声波扰动频率的增大而减小.

The influence of acoustic perturbation on wrinkle of premixed V-flame is dynamically analyzed. Wrinkle movement is measured by a fine thermal couple on a V-flame experimental bench. The influence of different frequency acoustic perturbations on V-flame wrinkle is measured. Both the analysis and the experiment results show that frequencies of flame wrinkle are the same as those of acoustic perturbation,and amplitudes decrease as frequencies rise.
