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

SINOPSIS

A numerical analysis has been carried out to investigate the hemodynamic flow through stenosed arteries having mild (S = 25 %) to severe (S = 65 %) occlusions and under different regimes of flow Reynolds numbers ranging from 50 to 400, considering laminar flow and modeling blood as both Newtonian and non-Newtonian fluid. Reattachment point, wall shear stress, and it's physiological aspects have been studied in detail. From the study, it is revealed that for all the cases a sharp variation in dimensionless wall shear stress (WSS) is observed near the zone of restriction. The maximum value of this peak WSS in the stenosed region is more sensitive to a change in the degree of occlusion rather than change in the flow Re. Atherosclerotic plaque formation tends to start from very low flow Reynolds number of 50 with 50 % restriction. For Reynolds numbers of 200 and above, it starts at 25 % stenosed condition.
