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

Spray nozzles operate by discharging a liquid sheet or jet which subsequently breaks up into droplets. Droplets which are too small can become entrained in ambient air currents and carried off target, while larger droplets often reduce coverage and efficacy. Many agricultural chemicals are formulated as an oil-in-water emulsion. In this study, single-phase (water) and two-phase (oil-in-water) emulsion were investigated photographically, experimentally, and theoretically to isolate the relevant mechanisms of sheet disintegration and representative droplet size. Three distinct mechanisms of sheet breakup were observed and parameterized by different scaling of the Weber number. Mechanisms include wave growth, rim breakup, and hole growth. Wave and rim breakup were found to dominate in single-phase sprays, while formation of holes within the liquid sheet and hole growth was dominant when an immiscible second phase was introduced. Existing models for wave growth and rim breakup leading to atomization, along with a novel model for hole expansion and subsequent sheet destruction, compare favorably with droplet diameters obtained experimentally. Although the exact mechanism for hole creation is not definitively established, several possibilities are discussed and inferred from experimental observations. It appears that a second immiscible phase, if low- or nonwetting, creates the necessary precursor for hole formation within the liquid sheet leading to sheet breakup. If this mechanism is indeed correct, it should be possible to control the spray droplet size distribution from spray nozzles given the size and wettability (hydrophobic nature) of solid or liquid immiscible particles/droplets within a two-phase system.
