摘 要: | 通过改变燃烧室头部喷嘴、旋流器的数目和位置,对短环形流燃烧室内有较强回流的湍流旋流流动进行了模拟。结果表明:在燃油和空气总流量不变的情况下,改变喷嘴数目对燃烧室出口平均温度、平均速度影响不大,但是,对出口温度分布、燃烧室内空气流场有较大影响。

Abstract: | Turbulent reactive flow in a short annular combustor is simulated by changing the number and location of nozzle and swirler in combustor dome.The simulation results show,under constant total mass flow of the air and fuel,the number of nozzle has little effects on the average outlet temperature and velocity,while it has a strong effect on the outlet temperature distribution and the air flow field in the combustor. |

Keywords: | short annular combustor combustion performance numerical simulation nozzle swirler |
