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

SINOPSIS

To visualize the flow field around the blade of the Wells turbine during hysteresis, experimental and numerical investigations were made including deep stall condition of the Wells turbine. The experimental investigation was made using a turbine-equipment with a simulated sinusoidal flow condition. The numerical investigation was made by an unsteady three-dimensional Navier-Stokes numerical simulation. A counterclockwise hysteretic loop is observed in unstalled condition, which can be associated with a streamwise vortical flow appearing near the blade suction surface. Besides, a clockwise hysteretic loop is observed in deep stall condition, the flow structure of which can be considered similar to that of the dynamic stall of an airfoil.
