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

Краткое описание

The modeling of laminar, fully-developed combined convection flow of a Bingham plastic in a vertical eccentric annulus, in which the walls are held at asymmetric constant temperatures is investigated. The momentum, continuity and energy equations are solved numerically using the Finite Element Method (F.E.M.). The results obtained are found to be in good agreement with the analytical solutions found by using a narrow gap approximation, that is the gap between the walls of the annulus is small compared with the inner radius. It is shown that different flow configurations exist depending on the buoyancy parameter, Grashof/Reynolds, including flow reversal and unsheared plug flow adjacent to the wall. If flow reversal occurs it is shown by the numerical solution that a pair of 'true plugs' in which the velocity is independent of both the radial and azimuthal variables can exist at each of the widest and narrowest regions of the annulus. Further, it is found that the leading order narrow-gap approximation is inadequate to predict these true plugs.
