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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

摘要

In recent times much work has been devoted to the issue of vortex definition in turbulence. Several criteria for vortex identification have been devised and techniques for defining the correspondence between different criteria have been found, leading to the possibility of representing nearly-equally intense vortical structures using different identification methods. The issue remains open of calculating a threshold value of the quantity chosen for vortex eduction, being able to give a physically based representation of the vortical structure at hand. For this purpose we present a direct method based on some statistics of the velocity field, applied in particular to the issue of representing a hairpin vortex in the wall region of turbulent channel flow.
