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

Краткое описание

Hot-wire measurements have been undertaken in a turbulent boundary layer in order to examine the combined effect of short roughness strip and localized wall suction on near-wall coherent structures. The short roughness strip is placed immediately after the suction strip and the suction is applied through a short porous strip for a range of suction rates. The results of Reynolds stresses indicate that the pseudo-equilibrium of the organized motion of the layer have been altered due to the suppression of the near-wall coherent structures. This is evident in the attenuation of the spectra and co-spectra relative to the undisturbed layer. Although, short roughness strip altered the magnitude and wavelength of the effect of suction on the layer, the results suggest that the short roughness strip and suction act independently on the mechanism of the layer.
