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

Краткое описание

An experimental study has been performed to analyze the role of fluid viscosity in ultrasonic atomization when excited with waves in the megahertz range. In the present experiments, liquid mixtures of water and glycerin have been atomized with a piezoelectric disk, and the atomization rate has been evaluated as a function of kinematic viscosity. Although atomization has been observed for viscosities as high as 28×10−6 m2/s, corresponding to a glycerin volume percentage of 80% at 35° C, the atomization rate drops almost by a factor of 10 before reaching 5×10−6 m2/s. Measurements have been obtained for a range of excitation voltages. Droplet size distributions have also been determined and they have been found to be nearly independent of both voltage and viscosity.
