| 摘 要： | 蒸发式V型稳定器是一种适用于加力式涡扇发动机加力燃烧室的外涵稳定器,本文在冷态实验中测量其流阻,同时在热态实验中测量其工作范围,并用大涡模拟对其冷态流场进行了三维全尺寸非稳态的数值模拟。分析表明,多处的回流区的组织有利于增加稳定器的稳定工作范围。

| Abstract: | Flow and combustion in a combustor using a V-gutter flame-holder with pre-vaporization for afterburners are studied by experiments and the cold flow is also studied by large-eddy simulation.The results indicate that this kind of flame holder can create multiple recirculation zones which lead to increasing the range of flame stabilization. |
