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

A novel concept of spray generator is described, which combines aerodynamic and mechanical liquid breakup to achieve liquid atomization. In particular, the concept of an air-blast (effervescent) atomizer is combined with the well-known stretch-and-fold mechanism commonly used in mixing high-viscosity fluids. The proposed technology is suitable to generate sprays of high-viscosity and non-Newtonian fluids, and in general enables liquid atomization at significantly lower pressures than conventional nozzles. A prototype spray generator based on this concept was designed, built, and tested with two fluids: an aqueous glycerol solution and a Carbopol polymer dispersion in water. For each fluid, the spray generator performance was studied changing the mass flow rates of fluid and air, and the rotation speed. Shadowgraph images of the spray were analyzed with a custom Matlab application to determine the cone angle and the drop size distribution.
