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 work studied the flow field induced by a blast wave traversing on a circular geometry. This was with a view to explaining the transient development of the complex flow structure that is formed when there is explosion that propagates a shock wave. Tests were conducted in a large scale experimental shock tube on a 200 mm diameter wall using a range of incident shock Mach numbers between 1.4 and 1.6. Schlieren optical system was set up to capture the images of interaction and the pressure history were recorded at different locations along the curvature. The results show series of lambda-shaped shocklets that later coalesced into a second shock. A shear layer evolved from the separation point and terminated by a vortex which enlarges as the diffraction process progresses. The flow later becomes unstable with two turbulent patches identified around the separation point. The present study gives information that is very useful in designing devices for the attenuation of blast waves.
