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

Department of Chemical and Process Engineering, University of Sheffield, Sheffield, United Kingdom Effervescent atomizers made from Perspex with rectangular-cross-section mixing channels have enabled a high-speed video study of the interaction between the internal two-phase flow and the external atomization process. Droplet sizes were measured using a laser diffraction instrument. The gas is seen to vent at sonic velocity in bursts along the axis of an annular liquid jet. Theoretical analysis indicates that the annulus is eroded by the Kelvin-Helmholtz instability ultimately exciting sheet instabilities. The relative contributions of the two instabilities, combined with coalescence of the smaller droplets, is considered to determine the differences between the size distributions generated by circular and slot-shaped orifices. Instabilities have also been observed in the liquid film on the wall of the mixing channel which degrade atomization quality. A new correlation has been developed for the liquid discharge coefficient which extends previous work on bubbly flows to the slug and annular flow regimes.
