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

ABSTRAKT

This paper reports an experimental investigation of the structure of the flow field around wall-mounted finite circular and square cylinders in an open water channel. A particle image velocimetry technique was used to conduct detailed velocity measurements in the streamwise-transverse and streamwise-spanwise planes. From these measurements, the iso-contours and profiles of the mean velocities and turbulent quantities were obtained at selected streamwise locations to document the salient flow features. The wake half-width of the square cylinder is 23 % higher than that of the circular cylinder but their spanwise spread rates are both linear and similar. The square cylinder generates more turbulence at its free end than the circular cylinder which is evidenced by the higher turbulent quantities. The proper orthogonal decomposition (POD) analysis revealed that for each cylinder type there are more energetic structures in the streamwise-spanwise plane than in the streamwise-transverse plane. There are also more energetic structures in the square cylinder than the circular cylinder.
