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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRACT

Results from the recent literature are reviewed to demonstrate the prevalence of modeling errors throughout the construction of eddy viscosity and Reynolds stress turbulence closure models for the Reynolds-averaged Navier-Stokes equations of incompressible flow. A straightforward analysis is presented to show the effects of these errors on the temporal development and spatial distribution of errors in mean flow quantities. This analysis indicates that solutions to the Reynolds-averaged equations can coincide with correspondingly averaged solutions of the Navier-Stokes equations only in the case that exact Reynolds stresses are employed in solving the Reynolds-averaged equations. In all other cases an O(1) error is shown to occur. It follows that computed results obtained from the Reynolds-averaged equations with typical turbulence closure models cannot be equivalent to correspondingly averaged solutions of the Navier-Stokes equations.
