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

RÉSUMÉ

Vortex shedding from a square cylinder in a channel is investigated by the numerical solution of the unsteady two-dimensional Navier-Stokes equations. A high order finite difference scheme is employed to solve these equations. The effects of walls on the vortex structure and drag coefficient are studied at different blockage ratios for the Reynolds number of 250 where the flow is laminar. Blockage ratios, A/H, vary as 0.17, 0.25, 0.33 and 0.5. Gap ratio between the cylinder and wall, s/A, also changes as 2.5, 1.5, 1.0, and 0.5. H and s represents the channel height and the gap between the cylinder and the wall respectively. The results reveal that the increase in blockage ratio strengthens the vortex formation. Reducing of gap ratio destabilizes vortex formation. For s/A = 0.5, vortex formation is suppressed.
