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: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRAKT

Rotor tip vortex formation and roll-up have been investigated using a flow visualization method coupled with a digital image processing technique. Emphasis is placed on the effect of the blade tip shape on the vortex structure and stability along its path. Particular attention is given to the influence of the tip geometry modification on the flowfield generated around the blade and its wake. For each blade configuration, the experiments include visualizations of the vortical structures generated by the blade tip and measurements of the tip vortex path. When compared to the rectangular tips, the evolutive tips are shown significantly to modify the wake geometry and to generate a dual vortex structure that produces a stronger instability of the tip vortex path. This vortex instability significantly affects the airloads distribution along the blade span.
