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

RÉSUMÉ

Near- and far-field atomization processes of impinging doublets are experimentally characterized using nongelled and gelled water as working fluids. The main emphasis of the study is on the effect of nozzle geometry, such as orifice inlet shape and aspect ratio, on jet stream surface dynamics and break-up processes before and after jet impingement, respectively. Gelled water jets (non-Newtonian), due to increased viscosity, display fewer surface disturbances than nongelled water jets (Newtonian). As a result, for a given flow rate the sheet formed by impinging jets is much more stable, and the corresponding break-up length is much greater for gelled water than for nongelled water jets. The nozzle aspect ratio has a more significant effect on the near-field jet stream characteristics for both fluids than the orifice inlet shape. Longer nozzles (l /d = 20) form more stable jet streams and delay the breakup of sheets, leading to greater breakup length than that attained with shorter nozzles (l /d = 5). For similar Reynolds numbers and hence, much higher respective flow rates, the droplet size for gelled water is much smaller than that for nongelled water. Also, impinging jets employing gelled water produce sprays with greater spatial distributions and wider ranges of droplet size than jets with nongelled water.
