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

Effect of longitudinal and transverse tube spacings has been investigated on the performance of staggered tube-bundles employed in fin-tube heat exchangers. The three-dimensional numerical study compares flow and heat transfer characteristics of tube bundles in the staggered arrangement confined between channel walls and subject to cross flow of air by using a finite volume-based developed computational code. For a steady laminar flow (ReD = 400), heat transfer and pressure drop characteristics in the presence of multiple pairs of vortex generators are presented. For fixed channel confinement, the flow Reynolds number and tube separations are varied. The objective is to identify the longitudinal and transverse tube separations of the staggered tube-bundle in the presence of vortex generators which would be associated with maximum enhancement in heat transfer and minimum pressure drop.

Palavras-chave: staggered tube bundle, vortex generator, longitudinal and transverse tube spacing, enhancement in heat transfer, reduction in pressure drop
