1.The influence of afterburning chamber length on secondary combustion efficiency and flow field were analyzed based on direct-connected ground simulation test.

1.结合直连式拟试验,分析了补燃室长度对掺混流场二次燃烧效率的影响。

2.Dispersity of gas flow can be enhanced and afterburning efficiency can be improved by increasing primary nozzle numbers and nozzle expansion ratio.

2.增加一次喷嘴的加大喷嘴的扩张比增加了燃气的分散性,提高了补燃效率。
