Abstract: Sustainability of future aviation platforms is heavily dependent on the lower emission capabilities of aeroengines which can be addressed by means of utilizing jet fuels of biological origin. Thus, an extensive experimental and numerical investigation campaign utilizing the Triple Annular Research Swirler (TARS) burner is started to understand the thermochemical properties and combustion characteristics of these fuels. The experiments are performed in atmospheric conditions with the TARS burner operated under various configurations of fuel injection, swirler combination and boundary conditions using methane and ethanol for gaseous and liquid fuel sources respectively. Preliminary results of the commissioning campaign for the liquid fuel operation of TARS burner integrated to atmospheric combustion rig are provided via chemiluminescence images. Moreover, the numerical investigations are conducted via Large Eddy Simulations in which kerosene-based (Jet A) and bio-grade (ATJ C1) jet fuels are used. The simulation results performed using operating conditions which will be targeted at the later stages of the experiments are analyzed to serve as a precursor to future measurements.
