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

Droplet dispersion for steady and transient sprays produced by an air-assist internally mixing cone atomizer is studied using high-speed laser imaging, shadowgraphy, and particle tracking velocimetry (PTV). For this spray, large droplets form close to the periphery while small droplets form close to the centerline. Radial dispersion of droplets is a function of droplet relaxation time and fluctuating flow characteristic times so that small droplets disperse more effectively in the radial direction than large droplets due to turbulent diffusion. For the transient spray, the overall axial and radial penetration of the spray is self-preserving and similar to penetration of starting continuous phase jets. Axial dispersion of droplets is a function of droplet relaxation time and the mean flow characteristic time. The leading edge of the spray exhibits higher turbulence than the trailing edge, which is characterized by very large eddies and smaller Reynolds numbers. The dispersion behavior at far-field away from the breakup region is expected to be similar for many dilute air-assist, internally mixing round sprays.
