This paper presents the combustion efficiency characteristics of an afterburner with bluff-body flame holders investigated with both numerical and experimental methods.
本文对装有钝体火焰稳定器的加力燃烧室燃烧效率特性进行了数值分析和实验研究。
The intensity of the gas backflow and axial swirl ond the dilution in the afterburner are enhanced by increasing the air-to-fuel ratio, and then the combustion efficiency is improved.
提高空燃比，可增强补燃室中燃气的回流和轴向涡流强度，加大掺混力度，从而提高燃烧效率。
