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

Viscoelastic liquids, such as paints and coatings, are widely known to be more difficult to atomize than typical Newtonian liquids. What is not known, however, is how such a difference affects spray coating in field conditions. To address this, we have examined the effect of a cross-flow on two different air-blast sprays, one comprising water and the other an industrial coating. Using particle image velocimetry and raw Mie scattering, we measured the penetration and dispersion of both sprays over a wide range of spray:cross-flow momentum-flux ratios: 134 ≤ qab ≤ 1382. For both sprays, increasing the relative momentum-flux of the cross-flow led to reduced penetration but enhanced dispersion. The leeward boundary, meanwhile, consistently outspread the windward boundary, creating a bias for which we have proposed several plausible mechanisms. As for differences between the two sprays, the coating droplets outpenetrated the water droplets because they had lower drag-momentum ratios, due to their larger size. In response to this finding, we have proposed a new regression model for predicting the penetration of sprays differing in mean droplet size. The coating spray also spread later and more abruptly than did the water spray, particularly at low qab. To explain this behavior, we have suggested a physical mechanism based on the delayed breakup of the coating ligaments.
