Under the national energy technology call for energy saving and emission reduction, the paper uses FLUENT software to simulate three-dimensional, two-phase, turbulent combustion in the combustion chamber of a certain type of aeroengine at the maximum and ground idle state and calculates the generation of CO and UHC. The value of temperature field, velocity field and concentration field. Through simulation, it is found that the maximum temperature of the flame is located at the axial position of the main combustion hole. The flame temperature begins to decrease after reaching the maximum temperature near the main combustion hole. In the temperature field of the combustion chamber outlet, the maximum temperature of the outlet section is 1820K and the average temperature is 1342K.The temperature distribution is relatively uniform overall. CO and UHC are mainly generated under low operating conditions, but the oil-gas ratio has a greater impact on pollutant emissions.
