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

RESUMO

Air Flow past three circular cylinders in tandem arrangement is simulated at 20 different Reynolds numbers ranging from 20 to 300. The spacing ratio L/D is set at 2, where L is center to center distance. The drag of all three cylinders is assessed with varying Reynolds number. Accordingly, pressure and velocity distribution in the near vicinity of cylinders is closely examined. It is found that Reynolds numbers of 42, 63 and 150 are critical Reynolds numbers for pressure, viscous and total drag forces respectively. Moreover, time evolutions of force coefficients are investigated to find the transitional Reynolds number at which the flow becomes unsteady and vortices are shed from the cylinders. It was observed that transition starts at Re 61; 101 and vortex shedding occurs at Re 61; 105 for the first time. Flow pattern is illustrated at a specific moment for all steady, transitional and unsteady states at various Reynolds numbers. Also, the time evolution of flow pattern is depicted for unsteady cases. It was observed that frequency of vortex shedding and also Strouhal number increase with Re.
