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

To determine the optimum combinations among geometrical parameters of multilouvered fins, a numerical study was performed with a two-dimensional finite difference code. The code was developed by the authors using an overlaid grids method. The numerical results showed that the existence of the optimum ratio of fin-pitch/louver-pitch for each louver angle. The effects of thermal wakes on the heat transfer characteristics were discussed from the numerical results to understand the correlation between the fin geometries and heat transfer characteristics. This discussion concluded that the control of the thermal wakes after louvers was a key point for the optimization of multilouvered fins. A simple numerical expression was proposed to estimate the optimum relation among the fin parameters. The numerical expression was evaluated through the discussion about the effects of the fin parameters and performance of heat exchangers composed of multilouvered fins. Also, it was obtained that a heat exchanger with smaller louver angle (θ) had superior performance in the range of 20° < θ < 30°.
