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

RÉSUMÉ

The formation of sprays of viscoelastic polymer solutions from flat-fan and pressure-swirl atomizers •was investigated experimentally. The fluids were characterized rheologically by means of a novel elongational device which allows the relaxation time and the steady terminal elongational viscosity of the fluids to he measured. These quantities turned out to be significant for the breakup of ligaments and drop formation from рrefilming atomizers. The elongational device furthermore quantifies differences between flexible and rigid polymers. With this rheological information and by means of dimensional analysis, the global nondimensional Sauter mean diameter of sprays from the flat-fan and the pressure-swirl atomizers is represented universally as a function of characteristic numbers. With the help of the same characteristic numbers, the volume fractions of small droplets in the sprays are quantified. These results are the basis of a design method for, e.g., agricultural sprays, where small fractions of small drops in the drop size spectra are required.
