摘要 借助凹腔火焰稳定器模型的数值计算结果研究了高总焓超声速流条件下凹腔火焰稳定器回流区中可能存在的稳焰机制。研究表明,高总焓来流条件下凹腔火焰稳定器回流区中至少存在着三种稳焰机制:回流区燃烧机制、回流区点燃机制和回流区整流机制。三种稳焰机制分别利用了高焓来流条件下回流区的三种不同特性:回流区燃烧机制利用了回流区的混合特性;回流区点燃机制利用了回流区的高温特性;回流区整流机制利用了回流区的阻流特性。计算结果表明,三种稳焰机制都有可能成为凹腔火焰稳定器回流区中起主导作用的稳焰机制。 In this research,the flame stabilizing mechanisms of cavity flameholder recirculation-zones in high total enthalpy supersonic flow were analyzed by numerical simulations.The analyses show,there were at least three flame stabilizing mechanisms of recirculation-zone in high total enthalpy supersonic flow: recirculation-zone combustion mechanism,recirculation-zone ignition mechanism and recirculation-zone adjusting mechanism.Three flame stabilizing mechanisms reflect three traits of recirculation-zone in high total enthalpy supersonic flow: recirculation-zone combustion mechanism reflects the mix trait of recirculation-zone;recirculation-zone ignition mechanism reflects the high temperature trait of recirculation-zone;recirculation-zone adjusting mechanism reflects the flow resistance trait of recirculation-zone.Numerical simulation results show three flame stabilizing mechanisms all have chances to dominate the flame stabilizing of cavity flameholders recirculation-zones in high total enthalpy supersonic flow.
