摘要

摘要:
本研究采用粒子图像测速技术（PIV）和平面激光诱导荧光技术（PLIF）从两个方向对单头部和三头部燃烧室的流场、喷雾场和燃烧室组分场进行同步测量。结果表明：低油气比工况下的火焰呈现V型结构，其稳定位置位于角涡区与主回流区交界剪切层；高油气比工况下火焰形态和稳定机制均发生了改变。单头部燃烧室的氮氧化物排放量从2 g/kg增加到了4.57 g/kg，而三头部燃烧室的氮氧化物排放量从1.28 g/kg增加到了9.99 g/kg，这是因为头部间相互作用会导致相邻头部的流场和火焰叠加，显著提升NOx的排放量，但CO和UHC等燃烧不完全产物未发生明显变化。本文揭示了头部间相互作用将通过影响流速、高温区体积的方式影响燃烧室排放特性，为航空发动机的研制工作提供了有力支撑。

Abstract:
This study employed simultaneous particle image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) to investigate the flow field, spray characteristics, and species distribution in both single-dome and triple-dome combustors from two distinct directions. The experimental results demonstrate that under low fuel-air ratio (FAR) conditions, the flame exhibits a distinct V-shaped structure stabilized within the shear layer at the interface between the corner recirculation zone and primary recirculation zone. At high FAR conditions, alterations in flame morphology and stabilization mechanisms were observed. The emission index of nitric oxide (EINOx) increased from 2 g/kg to 4.57 g/kg in the single-dome combustor, while showing a more substantial rise from 1.28 g/kg to 9.99 g/kg in the triple-dome combustor results from the aerodynamic-thermal coupling induced by flame-flame interactions promotes superposition of adjacent flow fields and flame. Conversely, the production of incomplete combustion products, including carbon monoxide (CO) and unburned hydrocarbons (UHC), remained statistically invariant. The experimental results conclusively establishes that flame-flame interactions in multi-dome combustor constitute a critical determinant of pollutant emission characteristics by modulating flow velocity, high-temperature zone volume, and high-temperature zone area, which provides valuable insights for the development of advanced aero-engines.
