| 摘 要： | 采用FLUENT软件对某型航空发动机燃烧室在最大和地面慢车状态进行三维、两相、湍流燃烧模拟,计算了CO和UHC的生成,获得了温度场、速度场和浓度场的数值。CO和UHC主要在低工况下生成,但油气比对污染物排放影响较大。

| Abstract: | By means of commercial software FLUENT,the temperature,velocity and concentration fields in an aero engine combustor are numerically calculated under the 3D two-phase turbulent combustion simulation of CO and UHC formation at maximum and ground idling operation conditions.CO and UHC are mainly provided under low operation condition,but gas-oil ratio greatly influences the pollutant emission. |
