| 摘 要： | 为了研究驻涡燃烧室拓宽燃烧边界的能力,设计了一种驻涡燃烧室实验件,并对其点火性能和贫油熄火特性进行了实验研究.驻涡燃烧室采用汽化器和蒸发管的组合作为供油方式,以煤油为燃料,实验中改变燃烧室的进口条件,测试其点火极限和贫熄极限.实验结果表明,采用蒸发管供油驻涡燃烧室具有良好的点火特性和贫油熄火性能.

| Abstract: | To investigated the ignition and lean blow out performance of a trapped vortex combustor(TVC)test rig,abundant experiments have been employed in variety inlet conditions.The TVC used a new type evaporating tubes as fuel injection manner,with kerosene as fuel.The results of the experiment indicate that the TVC could be used to extend combustion boundary. |
