In order to deeply understand the combustion characteristics of supercritical kerosene in aeroengine, a series of direct-connect experiments and numerical simulations were carried out under different ambient pressures and equivalent ratios based on a single-head model of an aeroengine dual-swirl combustion chamber. The influence of kerosene injection condition on combustion characteristics was obtained. The results showed that, under the same experimental conditions, the transition of kerosene from subcritical to supercritical condition had no obvious effect on the outlet center temperature, but it improved the outlet temperature uniformity to a certain extent, as the outlet temperature distribution coefficient decreased from 0.315 to 0.294. When kerosene was injected in supercritical condition, the uniformity of outlet temperature increased with the increase of equivalent ratio, as the outlet temperature distribution coefficient decreased from 0.294 to 0.195 at 380 kPa, and from 0.394 to 0.210 at 580 kPa. Numerical simulations of combustor flow field under various conditions were carried out based on our own CFD software, and the temperature distribution trend obtained was consistent with the experiments. The results showed that kerosene injected in supercritical condition can enhance fuel and air mixing, advance combustion, migrate the main combustion zone upstream and improve the uniformity of outlet temperature distribution.
