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

Oscillatory water flows in a branched tube were visualized by tracer methods to obtain a fundamental view of the flow phenomena effective for the enhancement of gas exchange in the human lung system. From the results, longitudinal vortices were found in the branched region, which were well known as the secondary flow vortices in a curved flow channel. The longitudinal vortices were observed to interact with the flow separation at the branch position, and to cause strong mixing. The effect of the longitudinal vortices on mass transport in the flow was studied from the measurement of the local concentration of the mingled ink in water in a curved tube where a pair of longitudinal secondary vortex was generated. The results revealed that the effective diffusion coefficient in the curved tube was about 3.2 times larger than that in a straight tube for the studied case.
