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

RÉSUMÉ

The results of numerical simulation of the development of streamwise Gortler vortices formed in unsteady circular Couette flow are represented. The vortices are initialized by injection of artificial vortical disturbances at given place of flow and at given instant of time. The problem of receptivity of the boundary layer in respect to the external disturbances is considered. The influence of the initial energy of disturbances, their wavelength, the location of input point and time of injection on the vortex characteristics are analyzed. A "cascade" mechanism of transport of disturbances from stability zone to the boundary layer has been identified. The features of formation and development of mushroom-shaped structures, in particular their uneven growth in transversal direction and subsequent increase of wavelength (Eckhaus instability) are explored.
