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

要約

Oscillation of a self-excited flip-flop flow, which exhibits multiple, uniform-flow rate jet streams, can be produced in a diamond-shaped cylinder bundle. This study concerns a fluid flowing through a duct stacked with a five-storied diamond-shaped cylinder bundle. Through utilization of the ramming effect, micro- and nano-sized bubbles are generated by supplying air through a pair of tiny holes drilled at each edge area in the narrowest cross section connecting the converging- and diverging-flow regions which are formed by two adjacent diamond-shaped cylinders. Individual nano-sized bubbles as small as 500 nm in the efflux can be visualized and recorded. The number versus diameter distribution is determined using a Multisizer III. Flow rates are varied to determine the effect of through-flow, Reynolds number, on the amount of nano-bubbles generated. The study has important applications in electronics industry as well as in biomedical technology.
