Abstract

This paper presents two techniques used to study peripheral parameters of non-evaporating high pressure diesel sprays from common rail injectors equipped with a twin-hole nozzle during the initial, highly transient stages. To characterise the spray, high speed optical imaging and X-ray radiography were used. The former was performed at the LTRAC laboratory at Monash University, while the latter was performed at the Advanced Photon Source at Argonne National Laboratory. The optical imaging made use of high temporal/spatial resolution spray recordings on a digital camera while the X-ray radiography relied on a point wise basis at roughly similar sampling rate. Results have shown some differences in spray tip penetration and jet merging length between two measurement types. Tip velocities were found much different from those typical of single-hole nozzles.
