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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRAKT

Two models for describing vortex rings: the Dyson's model with a continuous vorticity distribution and the vorton model with discrete vorticity distribution, which both can be used to describe the coaxial interaction of two identical vortex rings, are compared. The presentation of motion equations of both models in a similar formulation makes possible an extended analysis of both the analogies and differences between the models: comparing trajectories, impulses and energies of the vortex rings system in both cases for periodical interaction of two identical vortex rings in an unbounded fluid. The slightly different trajectories can be entirely explained theoretically from the respective equations of motion for vortex rings and vorton rings. The analysis of matching and comparison of the initial parameters of two different models, which both describe the same interaction, is presented in this article. A possible criterion, which can be used for description of a non-coaxial interaction of vortex rings by means of discrete vorton model, was obtained.
