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

The time-dependent Navier-Stokes equations in their streamfunction-vorticity transport form are numerically integrated to explore the early temporal stages of the evolution of vortical structures of different order in the near wake of a circular cylinder. The numerical technique used is a mixed spectral-finite analytic scheme in which the flow fields are expanded in Fourier series along the azimuthal direction and the convolutions arising from the convective terms of the vorticity transport equation are calculated by means of Fast Fourier Transform algorithms. The time advancement is performed by using a fourth-order Runge— Kutta algorithm (first four iterations) and a Predictor—Corrector scheme (subsequent iterations). The time-dependent case of a viscous incompressible fluid flowing around an impulsively started circular cylinder at the Reynolds number Re = 3000 (based on free-stream velocity and cylinder diameter) is considered, with particular attention to the evolution in time of primary, secondary, and tertiary vortices developing in the near wake of the cylinder numerically kept in its symmetric configuration. The results are presented for several time steps of integration mainly in terms of computer-generated images of streamlines and vorticity fields, describing the reciprocal interaction of vortical structures of different order in the near wake of the cylindrical body.
