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

Fluid flow in a small model of a Francis-type pump turbine was visualized by means of a tracer method and was imaged using a video camera rotating with the runner. The relative velocity vectors of the fluid flow were analyzed from the video images using a digital image processing technique based on the correlation method. The flow patterns are discussed in relation to the characteristics of the pump turbine. At a zero incidence inflow condition, the reverse flow zone on the suction surface of the blade is much less than that at a shockless inflow condition. Unsteady flow patterns at a low flow rate are also demonstrated. The problems that occur in the image processing measurement and the countermeasures are discussed.
