Experiment on spray distribution of an integrated strut flameholder with cross injection

  • 摘要:

    在常温常压、来流马赫数为0.182及液气动量比为10~70的条件下,以水为雾化介质,采用激光片光照相法开展了侧喷式一体化支板火焰稳定器的液雾分布特点研究,并探讨了液气动量比及喷射位置对液雾分布轨迹的影响规律。研究表明:侧喷式一体化支板火焰稳定器液雾分布的外轨迹与横向射流类似,内轨迹受稳定器回流区卷吸作用的影响而弯向回流区,且在低液气动量比条件下影响显著。液气动量比是影响一体化支板火焰稳定器喷雾内外轨迹的重要因素,液气动量比增加,液雾穿透深度增加。喷射位置对液雾外轨迹的影响较小,但对内轨迹影响显著;过近或过远的喷射距离均不利于回流区对液雾的卷吸,这与液雾喷射和稳定器的近距耦合有关。
