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: 1.1 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: 1.5 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: 0.5 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: 0.00018 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: 0.42 SJR: 0.217 SNIP: 0.362 CiteScore™:: 2.3 H-Index: 19

RÉSUMÉ

The concept of viscous dissipation in porous media is discussed. It is known that performing upscaling of the momentum equations of fluid continuum moving within porous material results in a set of unclosed system of equations. To get closure to this set of equations can prove very difficult, especially in nonperiodic porous media. Moreover, a set of length scale constraints needs to be satisfied for these equations to be adopted correctly. In this work, the upscaled momentum equation is used to derive an expression for the rate of change of kinetic energy. By slightly relaxing length scale constraints, new term appears that involve the dot product of the porosity gradient vector and velocity gradient tensor. Terms contributing to the conversion of kinetic energy into heat energy are separated and are collected in a single function named the dissipation function. This function is, however, different from that proposed in the literature and hence a resolution to this apparent controversy is needed. It is believed that any attempt to provide an expression for viscous dissipation in porous media should be based on the use of the upscaled equations and not on the semiempirical relationships that involve ad hoc terms.
