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

ABSTRACT

The evaporation of liquid droplets in sprays can be altered by interactions between closely spaced particles. We discuss a nonintrusive optical measurement technique that is based on the optical cavity resonances of the droplets to determine droplet sizes and evaporation rates. The addition of small amounts of Rhodamine 6G laser dye into ethanol or ethanol/ acetone mixture droplets allows the droplets to lose at discrete wavelengths that correspond to the spectral positions of the droplet-cavity resonances. Measurements of the cavity resonance shift as the droplet evaporates permits determination of droplet size changes with a sensitivity of 1 nm in droplet radius change for droplets with a radius of 40 μm. We have determined the variation in evaporation rates among the leading and trailing droplets within a single segmented flowing stream, as well as between adjacent droplets that are flowing within a closely spaced 3 × 3 square array of continuous streams. Qualitative fluorescence images of the vapor produced by a continuous single stream of flowing acetone droplets demonstrate the existence of a vapor trail generated by the leading droplets flowing at 10 m/s.
