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

摘要

In this study, we investigate the characteristics of blood flow in an artery with an overlapping unsteady stenosis. Due to the unsteadiness of the stenosis and its boundary effect on the blood flow system, the resulting flow is assumed to be unsteady with the same frequency as the one generated by the unsteady stenosis. The governing equations for the mass conservation and momentum are used for blood flow system, but here the dynamic viscosity of the fluid is a function of the radial variable as modeled by Einstein to take into account the hematocrit. Hematocrit is the percentage of the red cells by volume in the whole blood fluid. Mathematical models and computational codes are developed to determine the leading order flow velocity, pressure gradient, impedance and wall shear stress at the throats and at the critical height of the stenosis. We find that higher values of the frequency, hematocrit, and height of stenosis leads to higher values of the axial velocity, the impedance and the wall shear stress in the stenosis zone.
