Framing high-speed photography and single-shot photography wereused to observe the jets directly. The purposes of this study is to investigate the disintegrationand atomization processes at the velocity of 2km/s-3km/s as well as the auto-ignition andself-combustion of the light oil jets. Therefore, in the jet velocity measurement in addition to thehigh-speed photography, the results by other methods such as the laser beams cutting method and theshock wave detection using pressure transducers were also given. In the observation of the jetsevents, the illumination phenomenon was found, which may be regarded as the result of theauto-ignition and combustion of the light oil jets. Finally, the Munroe jet was studied.展开更多
