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

RÉSUMÉ

The gradient magnetic field introduced to convection heat transfer in a channel can result in longitudinal vortices in fluid flows. The laminar flow and heat transfer characteristics of air in a rectangular channel confined to magnetic bi-pole and quadrupole fields were numerically investigated. The velocity and temperature fields were obtained and the friction coefficients and Nusselt numbers were compared at different Reynolds numbers and wall temperatures for both hydraulically and thermally developing and fully developed flows. Different longitudinal vortices were presented for convection heat transfer in the magnetic bi-pole and quadrupole fields. The vortex-induced heat transfer enhancement was discussed by using the field synergy principle. The results show that the synergy between the flow and temperature fields can be improved by the magnetically induced longitudinal vortices. For hydraulically and thermally developing flows, the synergy between the flow and temperature fields in the magnetic quadrupole field was superior to that in the bi-pole field. For hydraulically and thermally fully developed flows, however, the synergy in the magnetic quadrupole field was worse than that in the bi-pole field.
