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

Краткое описание

It is common knowledge that, as the Reynolds number increases, flows lose their ability to damp out disturbances and they are increasingly composed of swirling eddies or vortices. This work proposes that the formation of inviscid flow arrangements is the mechanism that is responsible for these observations. Inviscid flow arrangements are flows of viscous fluids in which viscous forces vanish, not to be confused with inviscid fluids which have zero viscosity. The presentation begins with analysis of the viscous terms in the Navier−Stokes equation, showing that it is possible to arrange the flow of a viscous fluid so that viscous forces vanish, that these arrangements are vortex-like, and that inviscid arrangements are most likely to form in flow conditions corresponding to high Reynolds number. The author proposes that hurricanes, tornadoes, sink drain vortices, and turbulence are among the possible consequences. To the author's knowledge, this concept has not been presented in the scientific literature. A numerical study is then presented of laminar pipe flow subjected to a disturbance to determine if inviscid flow arrangements form and to study their behavior. An important emphasis is the inclusion of the disturbance in the Reynolds number. Using a novel method to visualize the deviation from laminar flow, inviscid flow arrangements are found to increasingly form as the Reynolds number increases. If it is true that inviscid flow arrangements play a key role in turbulence, then it is ironic that the phenomenon which increases the effective viscosity of a flow is actually a result of the tendency to eliminate the viscous force.
