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: 1.7 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: 1.4 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: 0.6 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

SINOPSIS

The present paper is intended to evaluate the local convective heat transfer of power-law fluids through a circular channel, accounting for the asymmetric heating that may occur in some practical applications. The temperature distribution within the fluid is analytically determined by assuming that the wall of the channel could be partially heated by a constant heat flux. The effects of asymmetric heating and the flow behavior index on the average performance of the heat transfer device are evaluated in terms of average Nusselt number, while the local phenomena are investigated by adopting the field sinergy principle approach. The results in terms of average Nusselt number highlight that the convective heat transfer coefficient decreases as the portion of the heated wall increases, while it increases as the flow behavior index decreases. This trend is motivated by analyzing the heat transfer phenomenon by means of the field sinergy principle approach; indeed, this analysis reveals that synergy between the velocity vector and the temperature gradient is better when the wall is heated only for a small portion and for shear thinning fluid.
