摘要

摘要: 在二元燃烧试验台上研究了一种新型变几何火焰稳定器的燃烧特性,重点描述了在不同试验工况下,稳定器燃烧效率、出口温度分布与稳定器几何形状变化的关系,并且通过稳定器的燃烧图像分析了几何变化对于燃烧状态及火焰结构的影响.结果表明:试验工况下,随着几何形状的改变,稳定器的燃烧效率呈现一定幅度的变化;尾缘槽宽与整流罩宽度比 w/h =1.25表现出其特殊性,在该点稳定器的燃烧状态和火焰结构发生较明显地改变;在稳定燃烧过程中,随着 w/h 的减小,出口截面中心温度不断升高,温度分布的均匀性降低.试验数据和结论有助于加深对该型变几何火焰稳定器的了解,并对该型稳定器的数值模拟和进一步试验研究有着重要的参考意义.

Abstract: A novel variable geometry flame-holder (“VGF” for short) based on v-gutter has been experimentally studied on a two-dimensionally combustion test-bed for its combustion characteristics .The effect of the change of gutter trailing edge width w on combustion efficiency and exit temperature distribution in different operating conditions was analyzed emphatically.Furthermore,the effect of the change of w on combustion status and flame structure was discussed by the combustion images in recirculation zone.Results show that: for the test conditions, (1) when w/h changes in 1.25~2.00, there is a certain range change in combustion efficiency.(2) w/h =1.25 shows specificity because the VGF combustion status and flame structure have changed at this point.(3) In the stable combustion condition,temperature of outlet cross-section center increases with the w decrease basically.Results and experimental data presented would enhance the phenomenological understanding of this novel VGF,and would contribute to the next experimental study and numerical simulation on it.
