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: 1.4 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 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

要約

We have applied a hybrid approach that combines the transient Reynolds-averaged Navier-Stokes (T-RANS) method for velocity and hydrodynamical turbulence with a direct numerical solving (DNS) of the magnetic induction equation for two-way coupled turbulent magnetohydrodynamic (MHD) flows. An originally developed electromagnetically extended two-equations (k-) eddy-viscosity-based model was used for the hydrodynamical turbulence closure. The validation of the hybrid approach was performed by simulating the Riga-dynamo experimental setup, which is characterized by an intermediate value of the magnetic Reynolds number (Rem 20) and a very high value of the hydrodynamical Reynolds number (Re 3.5 106). Numerical simulations provided all general features of the magnetic saturation regime with the frequency and amplitude of the generated magnetic field in good agreement with available experiments.
