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

Fractal dimensions of gas−liquid interfaces were measured in the breakup region of disintegrating liquid jets. The liquid jet was surrounded by an annular gas jet, and both were injected through a coaxial atomizer. The gas−liquid interface was categorized by a fractal set with dimensions and cutoffs that were found to be related to the physical processes of atomization. Using the fractal representation, it was possible to quantify the level of tortuosity of the gas−liquid interface and to examine its influence on both the stability of the liquid jet and the formation of droplets and their size distribution. The fractal dimension was measured as a function of axial location and a range of air and liquid velocities. The fractal dimension increases sharply from 1.0, at the nozzle exit, to a peak value at the breakup region, and then gradually decreases as the distance from the breakup region increases. It was found that the peak fractal dimension and the breakup point are at approximately the same axial location. The inner and outer cutoffs of the fractal sets are of the same order of magnitude as both the air turbulence length scales and the range of drop size. The average drop size was found to be proportional to an average interface length scale that was calculated based on the fractal representation.
