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

Several methods of deriving an expression for the spray cone half-angle of a swirl atomizer are presented. Expressions found in the literature, based on the inviscid theory, together with suggestions for improvements, are given. The theoretically derived functions for air core diameter and discharge coefficient as functions of atomizer constant that were presented in Part 1 of this article series are charted and compared with experimental results from the literature. Also, the various functions for spray cone half-angle, as a function of the atomizer constant, are charted and compared with the experimental results from the literature. The fit of these theoretical functions with the experimental results are discussed in terms of the flow physics and the limitations of the inviscid theory. This comparison leads to the conclusion that the inviscid theory may be of benefit in the basic understanding of the flow physics of swirl atomizer internal flow. However, it is of limited value for detailed understanding of the complicated flow regime as it does not consider variations in the supply pressure, viscosity, turbulence, wall effects, or fluid-gas interactions. It does allow ballpark estimates for flow rate and for air core size.
