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

The atomization mechanism of gas/liquid mixtures flowing through Y-jet atomizers has been studied by examining both the internal and external flow patterns. Air and water were used as the test fluids. Atomizers with transparent mixing ports were used to visualize the internal flow patterns, and the drop sizes were measured to examine the spraying performance. The liquid/gas momentum ratio was considered to be the appropriate parameter to describe both the internal flow and spray characteristics. A comprehensive physical model describing the atomization process is proposed; the process consists of "direct collision," "drop entrainment/deposition," and "liquid film disintegration." The validity of the model is also checked with the drop size distribution data. It is confirmed that the trend of the circumferential film thickness variation within the mixing port coincides with variation of the spatial distribution of spray drops.
