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

High-speed photography and impaction cards have been used to enhance knowledge of the manner in which droplets of Newtonian and non-Newtonian fluids break up in a high-speed jet of air. The photographs show that breakup was initiated for both types of fluid by the formation of waves on the surface of droplets exposed to the air stream, with frequency which depended on the velocity of the air jet, and with bags in the low-velocity regions behind the droplet and downstream of the peaks of the wave. The waves were subsequently stripped to form ligaments, initially joined by bags to form a web of ligaments and later separated into two parts as their central regions stretched, and droplets were formed within a distance of 20 diameters of the original droplet.
The non-Newtonian fluids have been categorized in terms of critical speed of breakup which increased with the addition of a copolymer to a critical velocity of 540 m/s. It is likely that higher concentrations of the copolymers than those examined here will lead to higher critical velocities. Additional experiments established that initial droplet diameters from 2 to 4 mm and the height from which the droplet fell into the air stream, 20 mm to 1 m, had little effect on the critical speed.
