Research Abstract

The multi-hole atomization enhancement nozzle developed in this study was obtained excellent spray characteristics, which the spread of the spray is considerably wide of about 50 degrees, the breakup length is short and the Sauter mean diameter is considerably small of about 10μm, atomization characteristics of the spray was improved. Moreover, the volumetric flow rate was increased about 2.5 times at the same injection pressure. Although the spray tip penetration of the multi-hole nozzle is short, the spread of the spray is considerably large about 3 times as large as the previous single hole atomization enhancement nozzle, high-dispersion spray was obtained. Furthermore, the injector, which was designed for high-viscous liquid based on the atomization enhancement nozzle, the spread of the spray becomes large significantly and the droplet diameter becomes small, the excellent spray was obtained independent of kinematic viscosity.
