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

Results are presented from analyses of liquid breakup regimes in which fuel slingers have recently been found to operate. A result is obtained for the liquid film thickness t that provides the proper length scale for correlating the atomization performance of slingers operating in the supercritical film-mode breakup regime. A corresponding result is also found for the subcritical ligament diameter d' that correlates the atomization performance of slingers operating in the subcritical film-mode regime. The transition between these modes is shown to scale as Wet1/2. Corresponding results are also presented for noncircular channel shapes. An analysis of in-channel Coriolis effects indicates how such liquid accumulation can be avoided. Slinger atomization performance is shown to correlate with a Weber number based on the appropriate length scale that governs the liquid breakup regime in which the slinger operates, with only a weak residual Ohnesorge number effect. Available data on slinger atomization performance are found to correlate well with the present results.
