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: 1.5 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 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

要約

The numerical treatment of the boundary conditions (BCs) in the computational domain is of paramount importance. In the passages formed by tube bank fins, a recirculation flow may occur at the outflow boundary. One of the conventional approaches to prescribe this kind BCs is to extend the computational domain far from the domain of interest, thus it waste the computing resource and lacks in a proper physical basis; while the convective boundary condition is somewhat difficult to implement and also lacks in a proper physical basis for elliptic-type problem. To find a more reasonable implement, firstly, the present study illustrates the quantitative similarities of the velocity components on those cross sections located at the periodic counterparts of the outflow boundary in the passages formed by the multi-row tube bank fins, and then a new method to specify the outlet flow BCs is introduced based on the quantitative similarities. If the proposed method is used, the simulation domain does not need to be extended and the possible recirculation flow at the outlet can be specified. The reliability of the proposed method is tested through comparing numerical results with experimental ones. The numerical results using the proposed and the conventional methods are also compared. The results show that the proposed method is feasible and can obtain reliable averaged characteristics with acceptable discrepancy.
