Schadstoffe in der Luftfahrt, Einzelaufgabe Nr. 2227. Experimentelle Untersuchung des Einflusses der Luftfuehrung auf die Zerstaeubungseigenschaften einer Luftzerstaeubungsduese. Bd. 2 Abschlussbericht

In the article experimental results of model airblast atomization nozzles closely related to practical use are presented. They were investigated within a wide range of load for the model fluids water/air. for this the nozzle construction as well as the operation parameters were varied. The air passage, the distribution of air, the air-water ratios and the counterpressure at the nozzle outlet are essential influential parameters investigated. The spray images were visually assessed. Velocity, size and distribution of the droplets were measured by means of phase doppler anemometer (PDA) and taken into account in the assessment of the nozzle. The measurements were conducted under atmosphaeric as well as under raised pressure at the nozzle outlet. For the measurement with PDA through optical windows rinsing air was applied in some experiments, a fluid coating on the glass surface in others.
