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

In this paper, a 3D numerical investigation of the air side performance of the wavy fin surface is presented with the body-fitted coordinates. Results from local Nusselt number distributions on the whole wavy fin and plain plate fin surfaces show that the local Nusselt number decreases quickly along the flow direction and the values at the upstream are about 10 times of those at the downstream. Based on the results, a new type of the fin surface pattern with a wave located only in the upstream part (fin B) is proposed, and then the comparison of the new fin pattern with the whole wavy fin (fin A) and whole plain plate fin (fin C) is presented. The results show that within the range of the Reynolds number studied, the Nusselt number for fin B is only about 4% lower than for fin A and about 45% higher than for fin C; but the friction factor of fin B is about 18% lower than for fin A and only about 26% higher than for fin C. The comparison at the identical Re number shows that fin B has the best comprehensive performance among the three types of fins, followed by fin C and fin A. Within the range of the Re number studied, compared to fin C, the increased percentage of Nu/f of fin B ranges from 12.4% to 18.5%; compared to fin A, this percentage varies from 14.9% to 20%. It also can be seen that under the identical pressure drop constraint, fin B has the best performance too, followed by fin A and fin C. And under the identical pumping power constraint, fin B has the similar performances to fin A, and both of them are superior to fin C.
