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

A theoretical study is made to optimize the fin dimensions of a horizontal low-finned condenser tube having a new class of high performance fin recently proposed by the authors. The shape of the proposed fin is characterized by a monotonically increasing radius of curvature near the fin tip and a constant thickness near the fin root. Extensive numerical calculations with systematically changed values of fin dimensions and vertical bundle depth are conducted to optimize the fin geometry with HCFC-123 as a condensing fluid. The results are compared with those for a rectangular fin. The newly proposed finned tube shows a significantly higher heat transfer performance than the rectangular fin tube. For a typical operating condition and a vertical bundle depth of 30, the newly proposed finned tube with an optimized fin geometry provides an enhancement in the mean overall heat transfer coefficient of a factor of 5.8 over the smooth tube.
