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

要約

In the injection of a high-pressure swirl injector for direct-injection (D.I.) gasoline engine use, an initial spray (also called a leading spray or a preswirl spray [1]) is generated from the fuel downstream of the swirl grooves in the initial stage of the injection. This initial spray is almost unaffected by tangential forces, it has feeble swirl velocity, and it atomizes poorly. The initial spray has different characteristics and behavior than the main spray, such as larger droplet size, farther penetration distance, and irregular shape. Therefore, the air—fuel mixing process of the initial spray is quite different from that of the main spray.
In this study, the structure of the initial spray by a high-pressure swirl injector for D.I. gasoline engine use is analyzed from observation of the reconstructed images of a hologram. The origins of the initial spray are clarified by observing the spray structures with and without cleaning the injection hole, and by comparing the volume of the initial spray with those of the injector interior, such as the annular volume and tangential grooves. The droplet size distributions in the initial spray at different imaging times are investigated. The spatial distribution of the droplet size in the initial spray is clarified, as are the effects of ambient pressure on the characteristics of the initial spray. Finally, the temporal variations of droplet size of the whole spray at fixed position is studied by a laser diffraction-based method, and the results are compared to the holographic results.
