Influence of primary swirl offset on downstream flowfield of dual-swirl cup

  • 摘要: 双旋流杯具有良好的综合燃烧性能,在航空发动机燃烧室中已获得广泛应用。但其在装配过程中不可避免地会出现细微的安装误差,为了研究这些细微误差是否会对燃烧性能产生影响,需要更细致地研究双旋流杯局部结构和气动特征对下游流场的影响作用。因此,本文在常温常压条件下采用粒子图像测速(PIV)技术测试了双旋流杯下游冷态流场,探究一级旋流偏置对反向双旋流杯下游流场的影响规律。结果表明,随着一级旋流偏置距离的增加,在无量纲偏置量下游流场无变化,而当继续增加一级旋流的偏置距离时,下游流场会出现明显的偏移,这对旋流器的安装调试提供了参考。
