摘要
The mixing of fuel and air plays a pivotal role in enhancing combustion in supersonic regime. Proper mixing stabilizes the flame and prevents blow-off. Blow-off is due to the shorter residence time of fuel and air in the combustor, as the flow is in supersonic regime. The flame is initiated in the local subsonic region created using a flameholder within the supersonic combustor. This study aims to design an effective flameholder which increases the residence time of fuel in the combustor allowing proper combustion preventing blow-off and other instabilities.

燃料和空气的混合在增强超音速制度的燃烧方面起着关键作用。正确混合可以稳定火焰并防止吹风。吹风是由于燃烧器中燃料和空气的停留时间较短，因为流动处于超音速状态。火焰是在使用超音速燃烧器中使用火焰持有人创建的本地亚音速区域中启动的。这项研究旨在设计一个有效的火焰持有人，以增加燃烧器中燃料的停留时间，从而可以防止吹风和其他不稳定性。
