Addressing Alcohol Abuse In Gay Men

Abstract

This paper deals with an experimental study of the breakup characteristics of water emanating from pressure-swirl hydraulic injector nozzles. The experiments were conducted using two nozzles with different orifice diameters 0.3mm and 0.5mm and injection pressures (0.3-4MPa) which corresponds to Rep= 7,000-26000. The effects of Reynolds number on the spray angle and other atomization characteristics were studied. Three laser diagnostic techniques were utilized: Shadowgraph, PIV (Particle Image Velocimetry), and PDPA (Phase Doppler Particle Anemometry) for a complete study of the atomization process. The comparison among the three techniques compared well with each other. Limitations of these techniques in different flow regimes related to the breakup are provided. Results indicate that velocity exhibits a logarithmic decay axially. The diameter decreases away from the nozzle, however, at some distance, the droplets begin to coalesce to make the effective diameter larger. These effects are seen to be functions of Reynolds number.
