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

要約

The unsteady incompressible Navier-Stokes equations are solved numerically in primitive variables (pressure and velocity) for calculating the flow variables in a tube with multiple constrictions under the axi-symmetric approximations. The computation is carried over by taking a suitable transformation for multiple constrictions. The effects of multiple constrictions on a viscous flow field are investigated. The disturbances created by the constrictions are mainly concentrated in the exit of the last constriction. It is found that over the entire Reynolds number ranges studied here, the flow in the downstream of the constrictions is dominated by the strong recirculating flow associated with a shear layer. Oscillatory flow has been noted at the Reynolds number 175 for 75 % area reduction in four consecutive constrictions in a tube. The streamwise velocity components at different points in the downstream of the constrictions oscillate with frequency 1.1. The computed wall shear stress, pressure, and stream lines are also noted fluctuating in the downstream of the constrictions. The flow characteristics (such as central line velocity, pressure distribution, wall shear stress, and stream lines at different Reynolds numbers) are shown graphically, and their consequences in the human cardiovascular system are discussed at length.
