Effect of carbon deposit removing hole area on the outlet flow field of double-swirler

摘要

摘要: 采用粒子图像测速仪（PIV）试验研究了喷嘴套吹积炭孔面积对双级旋流器出口流场的影响.试验结果表明：随着吹积炭孔面积与双级旋流器开孔面积之比由0增大到0.24，回流速度下降，进入双级旋流器内部的回流气量减小.当吹积炭孔面积与双级旋流器开孔面积之比大于等于0.18，吹积炭气流会扰乱双级旋流器出口附近流场，破坏双级旋流器出口对称的双涡结构，吹积炭气流对双级旋流器出口流场的影响范围为X/D=0~0.8.

Abstract: Particle image velocimetry (PIV) was used to study the effect of atomizer shroud carbon deposit removing hole area on the outlet flow field of double-swirler. The result showed that, when the ratio of the carbon deposit removing hole area to the double-swirler area increased from 0 to 0.24, the recirculated air velocity decreased and less air was recirculated into the double-swirler. When the ratio of the carbon deposit removing hole area to the double-swirler area was more than 0.18, the carbon deposite removing air would destory the sysmmetrical double-vortex structure and disturb the outlet flow field, which with X/D=0-0.8 was critically influenced by the carbon deposit removing air.
