摘要

通过三维数值模拟和试验相结合的方法，针对航空发动机主燃烧室开展了火焰筒头部旋流杯设计参数对燃烧室性能影响的研究，其关键设计参数为副旋流器相对进气量和旋流数，关注的燃烧性能包括出口温度场分布、NOx排放量等.结果表明：数值计算获得的规律与试验的结论基本一致.随着副旋流器相对进气量的增加，主燃烧室出口温度场逐渐恶化，而NOx排放量略有降低；副旋流器旋流数偏离基准设计值时，出口温度场恶化，而NOx排放量随旋流数的增加而增加.

Abstract

Based on the three-dimensional numerical simulation and rig test

the effect of swirl cup's design parameters of head of flame tube

such as the relative flow rate and the swirl number of secondary swirler

on combustion performance of an aero-engine main combustor was researched. The researched performance includes the outlet temperature field distribution and nitrogen oxides (NOx) emissions.It is shown that the result of numerical simulation and rig test is consistent: with the increase of the secondary swirler's relative flow rate

the outlet temperature field of the main combustor deteriorates

and the nitrogen oxides emission slightly reduces;with the deviation of swirl number of the secondary swirler from the benchmark design value

the outlet temperature field deteriorates

while nitrogen oxides emission increases with the increase of swirl number.
