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 goal of this work is to improve our understanding of the primary breakup of jets from shear-thinning non-Newtonian liquids. We use direct numerical simulations (DNS) with the volume of fluid method for tracking of the liquid phase and piecewise linear interface calculations for a sharp interface reconstruction. We calculate the shear-thinning viscosity with the Carreau-Yasuda model. We use the inflow velocity profile as well as the shear-thinning properties as varying parameters for different simulations. Different methods of investigation are presented and applied to the simulations. We visualize and describe the influence of shear-thinning viscosity on the breakup process. We quantify the breakup over the liquid surface area and show the influence of different inflow velocities and different shear-thinning viscosities on the breakup. The investigation is refined by analyzing quantities, which define the deformation of the jet surface. A new visualization method is used to track the temporal development of liquid mass. With these methods for analysis we lay a foundation to quantitatively compare different destabilizing parameters and to estimate droplet sizes resulting from the breakup. The combination of these analysis helps to provide a better understanding of shear-thinning breakup in general and brings us closer to predicting resulting droplet sizes.
