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

Краткое описание

It has long been hypothesized that the flight of birds and insects greatly benefits from the flexibility and morphing facility of their wings. A significant advantage that flapping flexible wing models have over quasi-steady rigid wing models was a much higher lift generation capability. Both experimental and computational studies have shown that the leading edge vortex (LEV) plays an important role in this higher lift generation. In this study, we further explore the internal mechanisms behind the production of these high lift forces. Two NACA0012 miniature wings, one flexible and one rigid, were actively plunged at various frequencies in a viscous glycerol-water solution. Two-dimensional, phase-locked particle image velocimetry (PIV) measurements were conducted to investigate the evolution of vortices. Simultaneous measurements of lift and thrust forces were taken during plunging to reveal the relationship between the force generation and the surrounding flow field. Results from the flexible hydrofoil were compared directly to results from the rigid one to reveal the influence of flexibility. These results can be used to benchmark future computational work.
