Abstract

This study was conducted to investigate the effect of cavitation on liquid jet atomization characteristics in nozzles of different length to diameter (L/D) ratios. For this purpose, a spray test facility with an ambient pressure chamber was constructed, and sprays were recorded using a high-speed camera for a wide range of conditions, which provided complete characterization of the orifice flow fields and the emerging jet. Collapse length measurements are provided and indicate the complex nature of the nozzle flow. Extensive discharge coefficient measurements for each nozzle are also presented. Finally, the influence of the length to diameter ratio on cavitation and subsequently on the spray structure is also addressed.
