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.

RESUMO

The present work shows a numerical study about laminar, steady and forced convective lid-driven square cavity flow with rectangular fin inserted on different cavity surfaces. The main purpose is to maximize the heat transfer between fin and cavity flow and evaluate geometry influence by means of Constructal Design. The problem is subject to two constraints: lid-driven cavity and intruded fin areas. The ratio between the fin and cavity areas is kept fixed (ø = 0.05). The investigated geometry has two degrees of freedom (DOFs), the aspect ratio of the cavity, which is H/L = 1, and the fin aspect ratio (H1 /L1) which is swept in the range 0.1 ≤ H1/L1 ≤ 10. The effect of the fin geometry over the spatial-averaged Nusselt number NuH is investigated for several Reynolds numbers: ReH = 10, 50, 100, 200, 500 and 1000. For all simulations the Prantdl number is fixed (Pr = 0.71). The fin is intruded in the middle point of three different surfaces of lid-driven cavity (upstream, downstream or lower). The conservation equations of mass, momentum and energy are numerically solved with the Finite Volume Method. As expected, fin geometry had strong influence over NuH for all evaluated ReH. The highest NuH was obtained for fins intruded in the downstream surface for 50 ≤ ReH ≤ 500, while for ReH = 1000, the intrusion of the fin in the upstream surface led to the highest thermal performance, i. e., the best shape and placement of the fin depends on the magnitude of ReH.
