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

ABSTRACT

The local and average heat transfer characteristics over a flat tube bank fin mounted with in-line vortex generators (VGs) with small longitudinal spacing (six VGs per tube) have been studied by using the analogy of heat and mass transfer. Three rows of flat tube and several types of surfaces involved in heat transfer process such as fin surface mounted with VGs, its back surface (mounted without VGs), and flat tube surface are considered. The effects of the fin spacing and VG parameters such as height and attack angle on heat transfer and pressure drop are investigated. The heat transfer performances of flat tube bank fin element mounted with VGs are compared with that without VG enhancement under three constraints. The correlations of Nusselt number and friction factor are given out. The results reveal that VGs can greatly enhance the heat transfer in the region near flat tube on the fin surface mounted with VGs, and in the region away from flat tube wall with some distance on the back surface of the fin mounted with VGs; that the in-line 6 VGs per tube mainly contribute to the increase of heat transfer on the back surface of the fin mounted with VGs; that increases of VG height and attack angle increase the enhancement of heat transfer and pressure drop; that Nusselt number is almost independent of fin spacing with flat tube width as the characteristic length; that small fin spacing causes great increase of pressure drop; and that at identical pumping power and identical pressure drop constraints, fin spacing has the main effect on the increase of heat transfer performance.
