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

The characteristics of the two-phase flow and the spray formed in an effervescent atomizer were experimentally investigated over a range of flow rates, gas-to-liquid ratios (GLR), injection pressures, and discharge orifice diameters. The Reynolds number (Re), defined with the orifice diameter as the characteristic length, was seen to be a pertinent parameter in addition to GLR for determining the transition from the bubbly flow to slug flow. The discharge coefficient of the atomizer in the bubbly flow regime and the Sauter mean diameter of the spray in the annular flow regime were found to scale with the parameter {GLR (Re)0.5}. The structure of the spray and the measured values of cone angle of the spray showed distinctly different features in the bubbly, slug, and annular flow regimes. A two-dimensional simulation of the flow and spray structure reproduced the gross features observed in the experiments.
