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

SINOPSIS

The wake of a leading droplet can influence a trailing droplet's behavior by altering the environment through which the trailing droplet travels. A high-ambient-pressure environment not only changes the result of any collisions by adding a strong shearing element, but the increase in aerodynamic forces also alters the droplet wake. Despite these effects, this work shows experimentally that classical small-perturbation theory for a cylindrical jet breakup into droplets holds over the range of ambient pressure from 1 to 70 atm. Further, the length of the stable droplet stream is controlled by droplet wake interactions and a droplet's ability to resist the inertial and shearing influences of the ambient gas. Secondary breakup transitions at high ambient pressures do not match those observed in isolated-droplet experiments. Collisions with satellite droplets at elevated pressures enhances deformation breakup significantly. Interestingly, shear stripping in a stream of droplets occurs in the Reynolds and Weber number regime associated with droplet deformation breakup in the isolated-droplet case. This rapid stripping phenomena may also be a result of wake interactions.
