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 detailed characterization of the interaction of a polydisperse spray with large-scale vortical structures in a jet is presented. Phase Doppler interferometry is used to acquire droplet size and velocity information. Planar imaging techniques are applied to document the distribution of droplets and their number density within structures. The presence of large-scale structures results in large local variations of droplet number density. Images taken through the cross section of a large-scale structure provide evidence that azimuthal structures contribute to the dispersion of droplets. Size measurements show that, in general, only droplets with Stokes number less than unity are found on the outer edge of vortical structures. However, even for very small droplets (Stokes number < 0.1), a substantial portion of the vortex center is void of droplets. Radial velocity measurements show that droplets have an outward radial velocity on the leading edges and an inward radial velocity on the trailing edges of structures. Axial velocity measurements show complex size-velocity correlations within structures among different droplet size classes. Size-velocity correlations become less distinct across the jet due to the transport of droplets by large-scale vortical structures.
