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

This paper numerically studies how the rib-pitch, rib-land, and rib-blockage ratios affect the axisymmetric turbulent flow and heat transfer in a reciprocating circular ribbed channel. The pitch ratio (rib-pitch to rib-height ratio of 8, 11, and 22), land ratio (rib-width to rib-height ratio of 0.5,1.0, and 2.0), and blockage ratio (rib height to channel diameter of0.05, 0.1, and 0.2) of rib were changed with a constant Reynolds number (10,000) under various Grashof numbers (~0−400,000,000) and pulsating numbers (0 and 4.64). The average time-mean Nusselt number in the circular ribbed channel is 94.44−184.65% greater than that in the smooth channel undergoing reciprocating motion. The combined effect between buoyancy, reciprocating force, and inlet fluid momentum enhances the heat transfer from the wall in the channel. The turbulent heat transfer from the wall is improved by increasing land and blockage ratios of ribs with decreasing rib-pitch ratio for the channel.
