1) lean blowout
贫油熄火
1.
By using flame propagation theory,2D two-phase turbulent combustion model,EBU-Arrhenius model,PSI-Cell model and ADINA software,the velocity,temperature and pressure fields at different flight conditions are calculated for an aeroengine when lean blowout occurs in the combustor.
应用火焰传播理论、二维两相紊流燃烧的k-ε模型、EBU-Arrhen ius模型、颗粒群轨道模型和AD INA软件,计算出了某型在研航空发动机在不同飞行状态下的主燃烧室贫油熄火时的流场、温度场和压力场;计算值与试验结果比较吻合,证实了数值模拟的合理性和可行性。
2.
The lean blowout fuel air ratio and flame photo were obtained.
对有两种头部的燃烧室进行了冷态流场的数值模拟,用粒子动态分析仪(PDA)测量了两种头部的速度场和喷雾场,结合慢车工况的贫油熄火试验结果进行了分析。
3.
