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

ABSTRACT

A microscopic system, consisting of a transmitted light microscope and constant-pressure flow vessel, is specifically designed to enable highly resolved high-pressure primary breakup investigations at engine-like densities. At first measurements diesel and two alternative fuels are injected with a standard diesel injector at different ambient pressures. Reynolds and Ohnesorge number are varied over a wide range and several individual mechanisms are identified: an asymmetric outlet flow, the formation of sheets, ligaments, and droplets, and finally the growth of azimuthal and transversal surface disturbances. Wavelength magnitudes of transversal disturbances are in good agreement with existing analytical theories of boundary layer instabilities. Azimuthal disturbances are associated with nozzle internal cavitation. For the given high Weber number azimuthal disturbances are mainly responsible for the overall shape and subsequent breakup of the jet core.
