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

A combination of visualization and local measurements of velocity and droplet size characteristics of normal and angled impinging sprays at an injection pressure of 80 bar, chamber pressures of atmospheric and 12 bar, and injection duration of 3.2 ms has shown the formation of a spray moving along the wall after impingement. Angled plates at 80° and 45° produced nonuniform wall sprays, with the difference between maximum and minimum radii from impingement increasing with plate angle. The penetration of the wall spray was less at the higher chamber pressure, and much of the injected fuel appeared to form a liquid film on the surface, although this could not be verified from the images. The velocities of the droplets inside the wall spray showed that its thickness was less at the higher chamber pressure with smaller velocities and larger diameters. The average droplet diameter was smaller than that in the spray prior to impingement for both chamber pressures so that they were better able to follow the induced airflow circulation. The results also showed that the 45° impingement resulted in similar droplets to those of normal impingement. In general, the droplets forming the jet wall spray with both angles were mainly transported from the main spray, with contributions from splashing and reatomization closer to the main spray and from stripping of the liquid film farther downstream, where the wall spray tended to turn upward.
