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

SINOPSIS

Three-dimensional symmetric computational fluid dynamics (CFD) simulations are performed to study the deformation and breakup of water drops in an air stream at different Weber numbers. The types of drop breakup considered lie in the bag breakup, the stamen breakup, and the sheet-thinning/ stripping breakup regimes. Symmetry conditions are assumed so that only one-quarter of a drop is simulated. A fully three-dimensional simulation is first conducted to justify this symmetry assumption which is then used in the remaining CFD simulations. In order to keep the drop within the fixed computational domain, the shifted Eulerian adaption (SEA) method has been developed. In this method all the field values are shifted back by one mesh cell after the center of the liquid mass has moved forward by one cell, while at the same time the boundary conditions are maintained. The CFD results reflect the behavior of the different breakup regimes observed in experiments. Further, the drop size distributions of each breakup regime obtained in the simulations are quantified by lognormal distributions. These product drop size distributions are consistent with the experimental observations and agree with simulation results reported in the literature. Furthermore, the dimensionless breakup times are in acceptable agreement with experimental values.
