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

摘要

A measurement was made of stream wise velocity fluctuation in a fully developed turbulent flow in an eccentric annulus. The experiment was performed utilizing two annular ducts of different radius ratios 0.308 and 0.48; in each case the eccentricity was varied from 0.25 to 0.75. The result indicates that the radial distribution of the relative turbulence intensity has a minimum value in the central region between inner and outer tubes. The variation of the relative turbulence intensity against φ has a peak value near φ = 3π/8, where φ is the circumferential coordinate of the bipolar coordinate system. The location of the minimum turbulence intensity approaches the radial position nearest the outer tube wall when the value of φ is close to 3π/8. Those results indicate that there is some difference between two regions of φ < 3π/8 and φ > 3π/8.
