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

The interaction of a spanwise vortex with a symmetrical airfoil has been studied experimentally at a Reynolds number of 2.5 × 104 based on the airfoil chord length. The smoke-wire visualization technique was used to examine the flow around the airfoil at angles of attack α = 0,5, and 10° for two different values of vertical offset between the vortex generator and the airfoil The results indicate an upwash effect on the airfoil as the counterclockwise vortex approaches the leading edge from left to right. The vortex-induced upwash causes the leading-edge separation for the airfoil at α = 10°, and the separation bubble formed on the upper surface increases in size during the passage of the vortex. In comparison with the head-on interaction, a larger scale of the vortex-induced separation bubble was observed for the case that the entire vortex core passes just above the airfoil at α = 10°, resulting in a flat plateau region on the upper surface pressure distribution.
