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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

A fluid flow and thermal transfer analysis in the presence of baffles was reported. Two various geometries of baffles, i.e., flat rectangular and V-upstream, arranged in overlapping in a two-dimensional horizontal channel of rectangular cross section were simulated in this paper. The governing equations, i.e., continuity, x-momentum, y-momentum, energy, turbulent energy, and turbulent dissipation rate, were discretized by the finite volume method and the SIMPLE algorithm was implemented. Effects of the V-shaped baffle angle (θ) were simulated to find the optimum thermal performance for the Reynolds number from 12,000 to 32,000. Four flow attack values are taken for the θ and which are 45°, 50°, 55°, and 60°, respectively. The impact of the V-baffle geometry on the heat transfer enhancement and fluid flow characteristics was illustrated and this is comparing the data of this configuration with those of the simple baffle.
