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 present numerical work reports the application of jets for modulating and eradicating the recirculation zone in the wake region behind a fully submerged two-dimensional square cross-section bluff body for high Reynolds number flow. The wake region of the bluff body is characterized by a strong recirculation zone and vortex shedding, leading to unwanted vortex-induced vibrations that may instigate structural damage. Jets of varying Reynolds number and center-to-center distance are explored to look into the most effective jet Reynolds number and jet spread in completely modulating the recirculation region. The numerical simulation is based on a two-phase volume-of-fluid model with open channel boundary conditions. The standard k-ω SST two-equation turbulence model is applied to close the time-averaged-momentum and continuity equations. The negative mean streamwise velocity signifies the recirculation region, and streamline contour plots are made to identify it. The variation in discharge velocity of the jet series is carried out for reallocation or complete disappearance of the recirculation region.
