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

SINOPSIS

Wall pressure fluctuations pt in an elastic pipe behind a local axisymmetric narrowing are studied. Sharp increase in the pressure pt in a finite region immediately downstream the narrowing and the presence of a pronounced pressure maximum upstream the point of jet re-attachment were found. The study of the wall pressure power spectrum, P(f), has revealed the low-frequency maximums in it. The maximums were found to be determined by the appropriate large-scale eddy structures in the regions of separated and reattached flow, and their frequencies were close to the characteristic frequencies of the eddies formation. A comparative analysis of the data for rigid-walled and elastic pipes shows that the wall elasticity causes the changes in the flow structure and the corresponding redistribution of the flow energy among the vortices. This results in the increase of the wall pressure amplitude and the level of the wall pressure power spectrum, P(f), at low frequencies, as well as appearance of new frequency components in this domain.
