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 up-to-date diesel engine, boost pressure has been increased to improve the thermal efficiency as compared with a conventional diesel engine. High boost pressure results in a high gas density condition in the combustion chamber. Therefore, the mixing process of a diesel spray under high ambient gas density conditions may be different from that of a conventional diesel engine. In this study, particle image velocimetry (PIV) was applied to measurement of the velocity field inside a diesel spray under a high ambient gas density condition. From the results of PIV measurements, the maximum velocity gradient positions inside a spray were evaluated, and the effect of ambient gas density on the maximum velocity gradient position was investigated. It was found that the maximum velocity gradient position relative to the spray periphery shifted from the spray periphery to the center of the spray with increasing ambient gas density. A local equivalence ratio distribution inside the spray was calculated in accordance with momentum conservation and the spray velocity obtained with PIV. It was found that the region with sufficient air for combustion shifted upstream with increasing ambient gas density.
