| 摘 要： | 高速燃烧室点火条件 高速燃烧室内通常存在外层的高速主动流,它不但用作燃烧的氧源,而且带动核心气体形成稳定火焰的涡流结构,同时还起隔离火焰与室壁的作用。它的外层一般情况下是净空气,内层掺有燃油。

| Abstract: | A jet screen ignition scheme has been developed based on the investigation of the ignition environment of the burning zone in the high speed flow combustor.It features a short time change of the flow pattern in the high speed flow near the wall during the ignition period,which is caused by a thin and bend high speed gas jet.A specially designed ignition experiment on a model of an aerogasturbine combustor verified success of the proposed scheme and showed its potentiality in enlarging the ignition range of the high speed flow combustor. |
