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

结合直连式地面模拟试验,分析了补燃室长度对掺混流场和二次燃烧效率的影响。

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

增加一次喷嘴的数目和加大喷嘴的扩张比增加了燃气的分散性,提高了补燃效率。
