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

SINOPSIS

This article presents experimental results on the breakup behavior of liquid jets emanating from elliptical orifices with different orifice aspect ratios. The experiments were carried out in the range of mean jet velocity 0−5 m/s, using water as the working fluid; the liquid jets were injected vertically downward in still, ambient air. Photographic methods were employed to analyze the breakup characteristics of the liquid jets. The breakup curves of the elliptical orifice jets are compared with those of circular orifices with the same exit area as the elliptical orifices. The comparison shows that the liquid jets emanating from the elliptical orifice are less stable than jets from the circular orifice in a particular range of flow conditions corresponding to a √We range of 2−20. We attribute this enhanced instability of the elliptical jet to the axis-switching process occurring in this √We regime, a phenomenon by which the elliptical jet interchanges major and minor axes periodically as the jet flows downstream. The breakup process of the elliptical jet resembles that of the circular jet below this range of flow conditions, and their breakup curves coincide. Above this range, the elliptical liquid jets exhibit different flow behavior from the circular jet, although their breakup curves coincide again.
