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

SINOPSIS

Visualization of coherent eddies in fully developed turbulent channel flows based on the scaling with characteristic variables associated with wall-bounded turbulence is performed using the results of the direct numerical simulation (DNS). DNS databases obtained by solving three-dimensional Navier-Stokes equations with different Reynolds number, based on the wall friction velocity and channel half, are employed to perform the visualization. The main objective is to assess the suitability of the characteristic variables of turbulence for direct visualization of coherent eddies in the instantaneous flow fields. Normalization variables used for turbulent statistics are examined to judge the best scaling variables of coherent eddy. The results show that the coherent eddies in fully developed turbulent channel flows is best visualized when scaled with Kolmogorov scale. The streamwise and the hairpins (loop-like) can be visualized simultaneously. The simulation results may provide an important insight to uncover behaviors of coherent eddies in turbulent flow fields.
