The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

SINOPSIS

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 L/D 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 mm), and grow with radial distance from the centerline (6–8 mm at the spray periphery). Volume fractions greater than 1% are seen at the spray centerline, and, once the spray has developed, the majority of the 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.
