Abstract
The breakup, penetration, atomization, and dispersion of a plain jet of kerosene Jet A-1 fuel in a non-swirling crossflow of air were investigated experimentally at test conditions relevant to LPP (lean premixed prevaporized combustion) for gas turbines. Measurement techniques employed include time-resolved shadowgraphs, Mie-scattering laser light sheets, and Phase-Doppler-Anemometry (PDA). The nozzle diameter was 0.45mm and its L/D ratio was 1.56. Air velocities lay between 50m/s and 100m/s, the air pressure range extended from 1.5bar to 15bar and the air temperature was 290K. Fuel flowrates were chosen so that the fuel-to-air momentum flux ratio q (q=(rliq*vliq2)/(rair*vair2)) assumed mainly values between 2 and 18.
