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

ABSTRACT

The turbulent flow downstream of a single square grid is being experimentally investigated in a relatively small-sized wind tunnel. 2D LDV (Laser Doppler Velocimetry) measurements are conducted at the centerline of the channel for Reynolds numbers ranging from 8300 to 24870. Two grids are tested with two mesh sizes (M) and the solidity coefficient is always kept constant. We aim at discussing the influence of the position of virtual origin x0 on the turbulent macro (Lf), micro (λf) and Kolmogorov (ηK) length scales. Five possible virtual origins (0 < x0/M < 8) are arbitrary chosen based on a literature review. Whatever x0/M is, we demonstrate that macro, micro and Kolmogorov length scales can be predicted by empirical laws according to some confidence intervals of 30, 20 and 15 % respectively. Comparisons with others experimental data are also provided to validate the model. Best choice for the virtual origin is also provided for the present set of experiments.
