Abstract

Abstract

Considering the structural optimization and fuel injection optimization of integrated afterburner, the effects of flame arrester position and fuel injection configuration on combustion characteristics of integrated afterburner were investigated based on the SST k-ω turbulence model and the non-premixed combustion model. The distributions of temperature field and velocity field were discussed, and the distributions of fuel droplets, oxygen, carbon dioxide and water were explored. The combustion characteristic and mechanism were elucidated through the field synergy, and the thermal flow field and combustion performance were evaluated based on the axial distributions of total pressure recovery coefficient, temperature uniformity coefficient, and combustion efficiency. The results showed that three recirculation zones existed in the combustion chamber. The bottom of central cone was a reverse recirculation formed by the sudden expansion of internal intake duct. The upper recirculation zone near the fuel injection rod was caused by the impact effect of external inlet on flow field, and the lower recirculation zone was caused by the opposing impact effect of external inlet and internal inlet. As the position of flame arrester shrank inward, the combustion in the below small space was enhanced and the combustion in the above large space was weakened, resulting in a weakened combustion performance. By comparing the combustion efficiency of different fuel injection configurations, when the upper, middle, and lower fuel injection ratios were 3∶1∶2, the afterburner exhibited the best combustion performance.
