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

This paper presents an experimental investigation on the kinematics of horseshoe vortex around a flat plate. In order to have a comparative study, the velocity measurements within clear water equilibrium scour hole at circular, square, and equilateral triangular piers of sides equaling the width of the flat plate are also taken by an acoustic Doppler velocimeter. The contours and spatial distributions of the time-averaged (mean) velocities, turbulence intensities and turbulent kinetic energy at different azimuthal planes (0° that is at the upstream axis of symmetry, 45, and 90°) were deduced. Velocity vector plots of the flow field at azimuthal planes were used to show further flow features. The vorticity and circulation of the horseshoe vortex were determined by using forward difference technique of computational hydrodynamics and Stokes theorem, respectively. The horseshoe vortex flow and turbulence characteristics were discussed from the standpoint of similarity with velocity and turbulence intensity characteristic scales.
