Droplet diameter and volume fraction measurements are reported for three different fuels (diesel fuel, dodecane, and methyl oleate) as a function of radial position within a pressure-atomized spray typical of diesel systems, Injection system parameters were peak pressures of 62 MPa and a single orifice injector with a 0.31-mm orifice diameter and an LID ratio of approximately 2. Results are for individual injection events into atmospheric-pressure and ambient-temperature air at an. axial distance of 25 mm from the nozzle. Measurements relied on infrared scattering, which was specifically chosen due to the high droplet number densities of these sprays. Details of the measurement technique are presented along with results. Results indicate droplet diameters are the smallest at the spray centerline (2-3.25 mum), and grow with radial distance from the centerline (6-8 Pm at the spray periphery). Volume fractions greater than 1% are seen at the spray centerline, and, once the spray has developed, the majority of he mass is contained in the central 0.75-mm-radial region. Spray details presented include the definition of transient time periods for the spray, the spray width as a function of time, the coupling between injection pressure and observed diameters (SMD) and volume fractions, and the differences in the spray properties as a function of fuel type.
