| 摘 要： | 在空气进气参数不变情况下，分析了喷口布局、喷口形状、头部型面对冷流掺混效果的影响。结果表明，燃气喷射方式不同，掺混在补燃室中的发展过程也不同，提高补燃室内整体掺混度的方法，不一定能提高头部的掺混度；可提高头部掺混度的燃气喷射方式有5孔交汇喷射、5孔偏心喷射以及头部采用椭球型面。

| Abstract: | The effects of several fuel-gas jetting parameters on mixing effectiveness were analyzed under the same air inlet flow, such as distribution and shape of jets and head-end profile. The results show that developing process of mixing in afterburning chamber is different along with the change of fuel-gas jetting modes.It is uncertain that the method to improve integral mixing degree in chamber will raise head-end mixing degree. The following modes can be used to enhance mixing effectiveness, including five-pore intersecting jetting, five-pore eccentric jetting and elliptical head-end jetting. |
