N2 - Towards the implementation of alternative jet fuels in aviation gas turbines, testing in combustor rigs and engines is required to evaluate the fuel performance on combustion stability, relight, and lean-blow out (LBO) characteristics. The objective of this work is to evaluate the effect of different fuel candidates on the operability of gas turbines by comparing a conventional petroleum-based fuel with two other alternative fuel candidates. Numerical investigations are performed to examine the performance of these fuels on the stable condition close to blow-out and LBO-behavior in a referee gas turbine combustor. Large-eddy simulations (LES) are performed at stationary conditions near LBO to examine effects of the fuel properties on evaporation, gaseous-fuel deposition, flame anchoring.
