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

SINOPSIS

A new fin geometry approximating a dimpled louver in a multilouver configuration under a fully developed flow assumption is investigated. The calculations are conducted on three fin configurations. Cases 1 and 2 investigate the effect of imprint diameter, whereas Case 3 investigates the effect of introducing a perforation in the dimple imprint. It is established that the dimple imprint diameter has a minimal effect on the flow and heat transfer. However, the introduction of the perforation in the dimple changes the flow and heat transfer profoundly on the dimple side of the fin by eliminating any recirculation regions in the dimple and generating higher intensity vortical structures. The introduction of the perforation increases the heat transfer coefficient between 12−50% with a corresponding increase of 15−60% in the friction coefficient.
