Abstract

In the present study, the effect of operating pressure on the flame response is investigated numerically, and the validity of atmospheric tests is examined. The results show that the flame shape significantly varies at atmospheric pressure, and the flame response to imposed pressure fluctuations is changed; therefore, atmospheric test stands are not reliable enough to study the combustion instability.

工作压力对涡轮发动机燃烧室火焰响应的影响

本文通过数值模拟研究了操作压力对火焰响应的影响，并验证了大气试验的有效性。结果表明:常压下火焰形状变化明显，火焰对施加压力波动的响应发生变化;因此，大气试验台对燃烧不稳定性的研究不够可靠。
