摘要

在来流温度773~1 073 K、来流马赫数020~032及常压条件下

试验研究了来流温度及马赫数对一体化凹腔支板稳定器(ICBSF)贫油熄火(LBO)性能的影响。结果表明:由于凹腔结构有利于燃油的蒸发与雾化

一体化凹腔支板稳定器的贫油熄火油气比为0001 3~0002 7

具有较宽的贫油熄火边界;与传统钝体火焰器类似

一体化支板稳定器的贫熄油气比随着来流马赫数的增加而增大

随着来流温度的升高而减小。此外

当来流温度显著增高时

来流马赫数对一体化支板稳定器贫油熄火油气比的影响变弱;同样

当来流马赫数显著增高时

来流温度的影响也变弱。

Abstract

The incoming air temperature was within the range of 773-1 073 K. The incoming flow Mach number ranged from 020-032. The results showed that

the lean blow-off (LBO) fuel/air ratio of integrated cavity-based strut flameholder (ICBSF) was within the range of 0001 3-0002 7 and had a wide lean blow-off limit because of the cavity structure favorable for evaporation and atomization of fuel. LBO fuel/air ratio of ICBSF increased with the increase of incoming flow Mach number and decreased with the increase of flow temperature

similar to that of conventional bluff-body stabilizers. When the temperature of incoming flow was significantly increased

the influence of the incoming Mach number on fuel/air ratio of ICBSF was weakened; similarly

when the incoming Mach number was significantly increased

the influence of the inflow temperature was also weakened.
