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: 1.5 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 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

SINOPSIS

This paper investigates the entropy generation analysis in a steady flow of two immiscible couple stress fluids in a horizontal channel bounded by two porous beds at the bottom and top. The flow is considered in four zones: zone IV contains the flow of viscous fluid in the large porous bed with low permeability at the bottom, zones I and II contain free flow of two immiscible couple stress fluids, and zone III contains the flow of viscous fluid in the thin porous bed with high permeability at the top. The flow is assumed to be governed by Stokes's couple stress fluid flow equations in the free channel. In zone IV, Darcy's law together with the Beavers-Joseph (B-J) slip condition at the interface is used, whereas in zone III Brinkman's model is used for flow. The walls of the channel are maintained at constant and different temperatures higher than that of the fluid. The closed-form expressions for velocity and temperature are derived analytically, and these are used to compute the dimensionless expressions for the entropy generation number and Bejan number. The effects of relevant parameters on velocity, temperature, entropy generation number, and Bejan number are analyzed and presented through graphs. It is observed that the porous plates act as smooth surfaces and reduce the viscous friction.
