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

The behavior of postimpingement diesel spray was investigated by comparison with that of a steady gas jet. Diesel sprays having various injection rates were injected into a high-pressure chamber. From high-speed photographs of the impinging process of the spray, the velocities just before and after impingement were analyzed as a function of the wall distance. The penetration coefficient of a postimpingement spray is defined and compared with that estimated by a simple momentum theory of a gaseous jet. Also, the effects of injection rate and its period on the penetration coefficient are discussed. Velocity deceleration occurred at the impingement point, controlled more by the impingement distance than by the injection period or the ambient pressure. Also, the characteristics of the diesel spray became nearer to those of the steady gaseous jets as the injection period became long. It is considered that the momentum loss caused by the wall friction is greater for the postimpingement spray than for the radial gaseous jet.
