摘要

参照单级旋流器设计方法

设计4种三级旋流杯中不同叶片数和叶片安装角第三级旋流器

采用particle image velocity(PIV)技术对三级旋流杯燃烧室流场进行研究.研究结果表明:随着第三级旋流器叶片安装角和叶片数的增加

主燃区的轴向速度逐渐变小

使得主燃孔射流作用增强;在同样叶片数情况下

增大第三级旋流器叶片安装角

使旋流强度增强;对于第三级旋流器不同安装角、第三级旋流器叶片数增加都使轴向速度变化趋于平缓

使燃烧室内主流受主燃孔射流扰动影响较小

流动更平缓.

Abstract

With reference to single-stage swirler design method

four kinds of third stage swirler of different blade numbers and installation angles in triple-stage swirler cup were designed. Triple-stage swirler cup combustor flow field was studied through the particle image velocity(PIV) technology. The experimental results show that with the increase of the third stage swirler blade number and installation angle

the axial velocity in main combustion zone decreases gradually

enhancing the effect of main combustion hole jet. Under the same blade number condition

the third stage swirler vortex intensity is boosted with the increase of the third stage swirle blade installation angle. For different third stage swirler blade installation angles

the flat trend of axial velocity increases with the increase of the third stage swirler blade number

making the effect of combustor flow disturbance decreases by main combustion hole jet and the mainstream flow more smoothly.
