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

摘要

It is experimentally demonstrated that an intact liquid jet can be induced to atomize by imparting periodic external forcing at the jet nozzle. The induced atomization can take place only in small discrete bands of the forcing frequency. In these bands of frequency, the external forcing appears to promote a new kind of interfacial instability that, instead of producing the usual large Rayleigh drops, breaks the outer layer of the jet into droplets much smaller than the jet diameter. The core of the jet remains unatomized. The maximum power delivered to the nozzle is 2.7 W. This small power input appears insufficient to atomize the entire jet. At the same exciting frequency, the induced atomization produces smaller droplets for fluids with lower surface tension. For the same liquid, the atomizer can produce different sizes of droplet ranging from 8 to 40 μm by use of different forcing frequencies ranging from 17 to 100 kHz. Thus, the atomizer is capable of rendering tailored atomization.
