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

ABSTRACT

Vortical structures that develop past the lower portion of the Ahmed car model (in the φ = 25° slant-angle configuration) have been studied numerically. Numerical simulations are executed (at ReL = 2.88 × 106) by means of a finite-volume computational code following the LES approach, and the results are compared with the experimental data obtained by other authors at the same value of the Reynolds number. For further investigation of the flow fields, the method of the imaginary part of the complex eigenvalue pair of the velocity-gradient tensor (λci or swirling-strength criterion) is applied to the velocity field to extract the turbulence vortical structures
. As a result we found that vortical structures of arch type generate from the lower portion of the body, in particular the plane-channel-type zone that is included between the floor of the computational domain and the external side of the body bottom characterized by alternatively high and low turbulent kinetic-energy contents.
