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

RESUMO

This paper presents the results of a numerical investigation of heat transfer and friction for the flow of air in passages with attached and detached rib arrays. This technique is used in internal cooling methods. Four geometric configurations are used in the calculations. The governing equations are solved in a two-dimensional domain using a finite-volume formulation. The SIMPLE algorithm for the velocity-pressure coupling is employed. The results are obtained for Reynolds numbers ranging from 200 to 1000. The rib height and rib width-to-channel hydraulic diameter, detached distance-to-height rib ratio, pitch-to-height rib ratio, and Prandtl number are fixed at h = w = 0.2, C = 0.5, p = 10, and Pr = 0.71, respectively. The grid is nonuniform and highly concentrated close to the rib to capture high gradient velocity, pressure, and temperature. A uniform temperature through the ribs and all walls was assumed. The interaction between the hydrodynamic and thermal structures is developed. The effect of geometrical configurations on flow and heat transfer has been detailed by a systematic analysis.We have determined the distributions of velocity, friction factor, temperature, and Nusselt number according to the different geometrical configurations and Reynolds numbers.
