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: 2.3 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: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.2 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

要約

Enhancement of bottom wall forced convection heat transfer rates in a ribbed cooling channel combined with differently shaped deflectors is investigated numerically. Four deflectors, including the sloping board (Case A), convex curved (Case B), concave curved (Case C), and cylindrical (Case D) deflectors, are mounted on the upper-downstream side of the ribs. The heat transfer and flow features are analyzed and compared based on the validation of the turbulence model and careful study of the grid independence. The results show that the flow structures are deeply affected by the deflectors, accompanied by changes in the heat transfer and friction factor. Compared with the ribbed channel with sloping board deflectors, Case B can guide the mainstream fluid to compress the recirculating flow region located on the lee-side regions downstream from the rib and can enhance the heat transfer of the bottom surface, despite the increasing friction factor. It is noted that the decrement ratio of the friction factor in Case D is 7.0−12.4%. Based on this remarkable expression, Cases B and D contribute to better overall performance. This is due to their prominent performance in the heat transfer enhancement and diminished flow resistance.
