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

ABSTRAKT

A review of the existing literature about the formation of drops and sprays from viscoelastic liquids by single-fluid pressure atomization shows that there are not many models around for predicting the mean size of the drops. Our paper extends the finding by Liu, Z.H. and Liu, Z.B. (J. Fluid Mech., vol. 599, pp. 451–459, 2006) that liquid jets in the first wind-induced regime may be destabilized by non-axisymmetric deformations to the Rayleigh regime without any aerodynamic influence. We present models for the mean size of drops formed by the breakup of capillary axisymmetric viscoelastic liquid jets and of plane sheets. The former is based on Weber's equation for the optimum disturbance wavenumber for a Newtonian liquid jet, applying the correspondence principle. The latter is derived from the dispersion relation for a plane liquid sheet and used for predicting the Sauter-mean drop size in viscoelastic liquid sprays from pressure-swirl atomizers. Proper account for the influence from the liquid viscoelasticity on the formation of drops is essential. Influences from the molecular weight and flexibility or rigidity of the polymeric solute on the solution behavior upon deformation are represented by rheometrically accessible stress relaxation and deformation retardation times of the liquid.Mean drop sizes predicted by our models are in good agreement with experimental data.
