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: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

要約

For the purpose of understanding the effects of standoff distance and confining pressure on erosion characteristics of a cavitation jet, the collapsing process of a cavitation bubble was simulated with the volume-of-fluid (VOF) model. In the numerical simulation, the effect of initial distance between the cavitation bubble and the impact surface and the magnitude of confining pressure was analyzed on bubble collapse shape, collapse time, pressure impulse, and velocity of a micro-jet. The results reveal that the numerical calculation agrees well with experiments for the detailed collapse process of a bubble; the VOF model can accurately calculate the pressure impulse and the micro-jet's velocity, which are hard to measure in experiments. It is also thought that the cavitation erosion of cavitating jets on an impact target is mainly due to high-pressure impulse rather than the micro-jets formed during bubble collapse, because of the magnitude of the former being far more than the latter. The magnitude of the pressure impulse and velocity of micro-jets is closely related to the initial distance and confining pressure, which influence erosion characteristics of a cavitation jet.
