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

RÉSUMÉ

Experiments are conducted to study the wake flow patterns of two rectangular cylinders at a Reynolds number of 292. The cylinders are parallel to the flow direction. The gap ratio between the cylinders, dss/w, is fixed to 0.4/1. The results show that lifted streamlines inside the gap between the cylinders are entrained into a series of hair-pin vortices at farther downstream locations. The hair-pin vortices are formed from the combined wake of the cylinders and are lifted farther away from the bottom wall while they are being swept downstream. The scale of the hair-pin vortices is relatively large as compared to the boundary layer thickness of the incoming flow.
