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

The combined effects of a free stream velocity pulsation of controlled frequencies and a high blockage ratio on the vortex shedding from bluff cylindrical bodies have been studied. This study includes signal quality behind the bluffs, power spectral density, signal to noise ratio, amplitude variation of velocity profile, and Strouhal-Reynolds number correlation. The Reynolds number based on the bluff's characteristic dimension, d is kept in the range 1000−6000. Two circular bluffs of dimensions 20 and 32.1 mm and a triangular cylinder of width 15 mm were used and positioned vertically in the test section. The effect of moderate frequency amplitude, up to 15 Hz, of free stream velocity perturbation on Strouhal number is almost insignificant for low blockage ratios but for higher blockage ratios the Strouhal number dropped by up to 10 % around Re ≈ 3000. The velocity amplitude decreased with increasing downstream distance from the bluff bodies. The blockage ratio did not have a significant effect on the SNR as the peak value remained in the range 40−50 dB. However, the Strouhal number increased with increasing tunnel blockage ratio.
