Abstract

Ab initio prediction of aeroengine sprays at realistic conditions is currently not feasible and will remain so for a significant time to come. As a partial solution to the problem, experimental data are generated to validate advanced combustion codes. For that purpose a generic injector was built and operated in an optical single sector combustor. Phase Doppler anemometry and Mie scattering were used. The in-house algorithm for the calculation of volume flux was modified to suit the experimental setup. Measurements were performed at 4 and 10 bars. Good volume flux density results can be obtained within the lift-off distance of the flame.
