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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

SINOPSIS

The interaction between vortical structures and turbulent events in the wall region of a turbulent channel flow is investigated numerically. The system of the incompressible Navier-Stokes equations is integrated by using a mixed spectral finite-difference numerical technique, following the procedure of direct numerical simulation (DNS) of turbulence. The value of the Reynolds number based on the wall-shear velocity and channel half-height is Reτ = 200. A specially assembled computing machine is used for calculations, including one Intel i7 quad-core processor and one Nvidia C-1060 Tesla device programmed using the CUDA paradigm. The swirling-strength criterion (or the λci criterion) for vortex extraction is applied to the fluctuating portion of the computed velocity field, and the process of interaction of hairpin vortices and turbulent ejection- and sweep events is confirmed.
