摘要:
 常温常压条件下,在单头部矩形光学可视燃烧室试验件上,开展了预燃级内级旋流对点/熄火性能的影
响研究,在此基础上,采用 PIV 和燃油 PLIF 光学诊断技术研究了火焰筒相对压降、预燃级燃油流量对流场结构
及燃油空间分布的影响,结合流场和燃油分布试验结果,分析了预燃级内级旋流对点/熄火性能的影响,结果表
明:预燃级内级有旋方案的点/熄火性能优于无旋方案,预燃级内级无旋将导致旋流器中心区域轴向产生高速正
向射流,这不仅会破坏回流区结构,而且会影响燃油核心区的分布,这不利于点火器附近核心火团的生成和回流
区火焰的稳定,最终导致点/熄火性能的恶化
Abstract:
 On single rectangular test-rigs,the effects of liner-relative-pressure-drop and pilot-fuel-flow on fuel
spray distribution and flow fields were studied by PIV and fuel-PLIF technology under atmospheric pressure and
temperature.On the basis of which the influence of pilot-inner-staged swirl on ignition and lean blowout was investigated.The results indicate that pilot-inner-staged swirl contributes to the improvement of the performance of ignition and lean blowout.High-speed axial jet-flow occurs in the center of the swirler without pilot-inner-staged swirl,
which will break the structure of recirculation and affect the core area of fuel spray distribution,thus exerting a
negative effect on the formation of kernel flame and flame stability,and finally leading to the deterioration of the
performance of ignition and lean blowout.
