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

In order to clarify the mechanism of the severe erosion that results from singular vortex cavitation, we carefully observed the vortex cavitation associated with the erosion around a butterfly valve by means of a high-speed video camera, whose maximum framing rate is 40,500 frames/s. The flow pattern of cavitation was observed using the “correlation method,” which is a digital image-processing technique for analyzing motion by means of a series of images. It is worth noticing the process of the vortex cavitation developing in the boundary between the main flow region, i.e., the orifice jet, and the recirculating region. We came to the conclusion that the cavitating vortex core consists of several tiny vortex cavitations. The rotating velocity of highly erosive vortex cavitation can be also detected by the technique.
