Description
Interrelationship between the phenomena in the pre-mixing duct and combustion chamber of an aero-engine lean combustor under combustion oscillations was studied at a realistic temperature and pressure. A research approach characterized by simultaneous kerosene/OH LIF and by use of an optically accessible main nozzle was successfully applied, which was developed in our previous studies. Phase-averaged image processing was performed and the effects of oscillation pressure levels on the fluctuation of kerosene/OH concentrations and fuel-jet trajectory angles were investigated. It was shown that the oscillation pressure levels did affect their fluctuation levels and phase-delay with respect to the oscillation pressure.
