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

A droplet in an airstream deforms and disintegrates into finer droplets by a complicated mechanism. We focus on bag-type and umbrella-type breakup mechanisms in the present study. Under conditions in which the relative velocity between a droplet and the airstream is low, the droplet breakup mechanism changes from bag-type to umbrella-type breakup with a small increase in the relative velocity. The airflow around a single deformed droplet was visualized and the velocity distributions were measured by particle image velocimetry. The droplet velocity was measured by high-speed video. The experimental results show that vortices are generated on the leeward side of the droplet. For the bag-type breakup, the vortices are generated alternately, similar to a Karman vortex. For the bag-type breakup, the upward air velocity toward the leeward surface of a droplet is less than the downward air velocity toward the windward surface. The relative velocity between the upward and downward air velocities bulges the droplet out like a bag. On the other hand, for the umbrella-type breakup, bilaterally symmetrical twin vortices are generated. The upward velocity is almost the same as the downward velocity. Therefore, the center of the droplet remains as a wick and the peripheral part of the droplet bulges out.
