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

RESUMO

Atomization characteristics in a mutual-impingement spray system was investigated experimentally. The sprays injected from two conventional electronic fuel injection (EFI) nozzles or spraying nozzles were impinged at various impingement locations and impingement angles. When the impingement took place in the vicinity of the nozzle, a jet-to-jet impingement was observed, while a spray-to-spray impingement was observed in the case of mutual impingement of fully developed sprays which formed far away from the nozzle. The results showed that the spray tip penetration in the case of jet-to-jet impingement became short compared with that of the free spray (nonimpingement). On the other hand, in the case of spray-to-spray impingement, the spray tip penetration was almost the same as that of the free spray. Also, the reduction of Sauter mean diameter (SMD) was caused by the film disintegration after the impingement in both cases, jet-to-jet and spray-to-spray impingement. The SMD after the jet-to-jet impingement was approximately one-half of that of the free spray. In the case of the spray-to-spray impingement, it was observed that the liquid film was formed by the droplet collisions in the spray and the film disintegrated into many fine droplets. The SMD reduction after the spray-to-spray impingement was about 70−80% of that of the free spray.
