| 摘 要： | 针对一种采用蒸发管供油的矩形单驻涡燃烧室试验段,采用高能电嘴直接点火方式,通过改变电嘴位置,电嘴深入到凹腔深度和电嘴能量,在不同主流工况下进行点火试验,找出针对特定结构和进气方式驻涡燃烧室的最佳点火位置。试验结果表明:这种结构的单涡燃烧室在主流温度623～723K,马赫数0.3～0.55范围都可以点火成功;主流温度增高以及电嘴能量增大有利于点火;电嘴深入凹腔深度增加并不能一定有利于点火;不同的点火位置表现出了不同的点火规律。

| Abstract: | To investigate the lean ignition performance of a new single rapped vortex combustor,experiments have been employed in variety inlet conditions,different spark positions,and different spark energy.The results indicate that as Ma of inlet conditions varies from 0.3 to 0.55,and temperature from 623～723 K,this type combustor can ignite successfully.Higher inlet temperature will be helpful for ignition.The effect of increasing depth of spark is not as good as expected.The disciplinary of ignition for different positions is not the same. |
