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

In the present investigation the complex flow past a delta winglet-pair placed in a rectangular channel is studied numerically using the Large eddy Simulation (LES) approach. The Reynolds number based on the channel height and inlet velocity is 10000. A grid of 165 × 45 × 95 is used. The code is based on Marker and Cell algorithm with third order upwind scheme for the convective term. The computed results are compared with experimental data at Reynolds number of 134000. The Reynolds number in computation is lower due to limitation of computing resources but the computations are able to capture the essential features and show qualitative agreement with experimental data. Computation show that the longitudinal velocities generated by the winglet-pair disrupt the growth of boundary layer and would serve ultimately to bring about enhancement of heat transfer between fluid and neighboring surface. Many features of flow, which are difficult to measure experimentally, can be obtained from the LES study.
