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

RÉSUMÉ

Fuel injection technology plays an important role in improving the thermal efficiency and reduction of exhaust gas emissions of diesel engines. In the nozzle of a fuel injector, cavitation takes place and enhances the atomization of fuel spray. In a multihole injector, an asymmetric inflow into the nozzle may play a dominant role in cavitation and discharged liquid jet. In this study cavitation in various nozzles with different needle lifts and different nozzle lengths with an asymmetric inflow and discharged liquid jet are visualized and analyzed. As a result, we conclude that (1) cavitation occurs asymmetrically due to the asymmetric inflow; (2) an asymmetric cavitation induces asymmetric liquid jet and spray; (3) thick and long cavitation is formed due to large lateral momentum at the inlet corner of the nozzle, which induces a large deformation of the liquid jet especially when the needle lift is small; (4) jet angle is large in short nozzles; and (5) a modified cavitation number which takes into account the flow contraction at vena contracta can be utilized to predict cavitation length in a nozzles with various needle lifts.
