摘要

为了解不同进口气流角对某回流燃烧室性能影响

进行了回流燃烧室性能试验.结果表明:不同的进口气流角度对回流燃烧室的出口温度分布影响不同

回流燃烧室中装配30°整流叶片的轴向扩压器时出口温度分布系数是无整流叶片的轴向扩压器时的1/2

而径向温度分布系数比无整流叶片的轴向扩压器时小得更多.不同的进口气流角对点火性能也有较大影响.

Abstract

In order to understand the effect of different inlet airflow angles on the performance of a reverse-flow combustor

performance experiments of reverse-flow combustor were carried out. The results show that

different inlet airflow angles have different effects on the outlet temperature distribution of reverse-flow combustor. Compared with the 30 degree vaned axial diffuser and the vaneless axial diffuser in the reverse-flow combustor

the oulet temperature distribution factor in the former is only half of the latter

and the radial temperature distribution factor is also much smaller in the former. Also

different inlet airflow angles have bigger effect on ignition performance.
