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: 0.7 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: 0.7 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: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

要約

An existing database of direct numerical simulations (DNS) representing mixing of species under supercritical pressure (supercritical-ρ) conditions has been investigated for the purpose of understanding the modeling of the gradient of the filtered pressure, the divergence of the filtered heat flux, and the divergence of the filtered species mass flux, all in the context of large eddy simulation (LES). The analysis consists of two separate parts. The activities of all terms appearing in the LES equations are first evaluated, and the dominant terms for each of the transport equations are identified. These data are used to check whether the standard LES assumptions−i.e., that the three above quantities are equal to the gradient of the pressure and the divergences of the fluxes computed from the filtered flow field, respectively−that are routinely used for atmospheric-ρ flows, continue to be valid also in the realm of supercritical-ρ conditions. Having found that these assumptions do not hold under supercritical-ρ conditions, alternative modeling strategies for these terms are proposed, and their accuracy with respect to the standard LES assumptions is assessed.
