摘要

摘要:
小槽宽蒸发式供油/稳焰一体化火焰稳定器具有火焰稳定性好、总压恢复系数高的技术优势，在未来宽域吸气式发动机加力燃烧室具有良好的应用前景，为了探究结构参数对小槽宽蒸发式供油/稳焰一体化火焰稳定器贫油点熄火特性的影响，在气流速度为40～115 m/s和气流温度为573 K条件下，在二元试验段内对不同槽宽和开孔率的小槽宽蒸发式供油/稳焰一体化火焰稳定器开展贫油点熄火试验及冷态流场数值模拟研究，研究结果表明：①开孔率增大，局部回流区涡数目增加，同时燃油气动雾化和蒸发增强，燃烧室点熄火油气比降低；②大开孔率火焰稳定器的贫油点熄火油气比随来流速度增加呈现先减小后增加趋势，小开孔率火焰稳定器的贫油点熄火油气比随来流速度增加持续减小；③槽宽增加，局部回流区涡系尺寸增大，同时燃油气动雾化和蒸发增强，燃烧室点熄火油气比降低。

Abstract:
With the advantages of good flame stability and high total pressure recovery coefficient, the small slot wide evaporative fuel supply/flame stabilization integrated flameholder has a good application prospect in the afterburner of wide-range aspirated engine in the future. To investigate the influences of structural parameters on the performances of the flameholder lean ignition and lean blowout, the lean ignition and lean blowout test and cold state numerical simulation of the flameholder with different slot width and hole ratio were carried out in rectangular test section under the condition of air velocity of 40—115 m/s and air temperature of 573 K. The results showed that: (1) with the increase of the hole ratio, the number of vortices in the local recirculation increased, the fuel atomization and evaporation were enhanced, and the ignition and lean blowout fuel/air ratio of the combustion chamber decreased; (2) with the increase of incoming flow speed, the ignition and lean blowout fuel/air ratio of large hole ratio flameholder decreased first and then increased, and the ignition and lean blowout fuel/air ratio of small hole ratio flameholder decreased continuously; (3) with the increase of slot width, the size of vortex system in the local recirculation zone increased, the fuel atomization and evaporation were enhanced, and the ignition and lean blowout fuel/air ratio of the combustion chamber decreased.
