Effects of airflow split and primary holes arrangement on lean blowout limits of combustor with dual-axial swirlers

  • 摘要: 针对采用双轴向旋流杯结构的某单头部矩形燃烧室,实验研究了头部进气面积及主燃孔布局对燃烧室贫熄特性的影响.实验结果表明:一、二级旋流器进气面积的变化对燃烧室贫油熄火性能有很大影响.一级进气面积增加20%可拓宽贫熄边界11.8%;二级进气面积增加20%可拓宽贫熄边界16.6%.相反,减小一、二级旋流器进气面积都使燃烧室的贫熄性能变差.此外,主燃孔布局的变化对燃烧室贫熄边界几乎没有影响.
