Abstract

The goal of the current investigation was to enlarge the existing dataset with penetration and atomization data for three different nozzle diameters. Kerosene was used throughout the tests but nozzle diameter, air velocity, pressure and the momentum flux ratio were varied. Shadowgraphy was employed to measure the liquid penetration and show the general spray characteristics. Droplet diameters, velocity- and fuel flux distributions were measured with a Phase Doppler Anemometer 100 mm downstream of the jet nozzle. In addition to momentum ratio, the jet penetration is also strongly influenced by the nozzle diameter. Concerning the droplet size the dependence on the nozzle diameter was small compared with the influence of air velocity and pressure. A correlation for these cases with a quotient of aerodynamic weber number Weaero and nozzle diameter D greater than 1.2E+06 of surface breakup is given.
