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

RESUMO

Motivated by the need to improve spray coating, an experimental investigation into viscoelastic atomization using preformulated model test liquids is presented. These test liquids had similar values of surface tension, density, and rate-independent shear viscosity, but varying extensional viscosity. Through the use of these test liquids, the effects of elasticity were systematically isolated and found to act against the breakup of a spray issuing from a plain-jet air-blast atomizer. Flash photography revealed large-scale filamentary structures at breakup, which delayed discrete droplet formation until farther downstream, where relative air-liquid velocities were reduced. The lower relative velocities near breakup produced an increase in the volumetric median diameter, as was confirmed by analysis of high-magnification shadowgraphs. The hindering influence of elasticity on atomization was further substantiated through particle image velocimetry measurements, which indicated that the elastic droplets, owing to their greater inertia, were better able to maintain their initial momentum.
