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

Coaxial airblast atomizers have many applications, including fluidized bed denitration in the nuclear industry and aerospace propulsion. Small droplet sizes at the moderate gas−liquid mass ratios are desirable in these applications. Experimental studies on a novel airblast atomizer, designed to control the droplet size using variations in the dimensions, are reported in this article. The inner tube of the atomizer housing liquid jet terminates in a bluff body face at the exit plane, on which an annular air jet forms a recirculation zone. Jet breakup is induced by the helical instability and shear of the coalesced droplets and liquid film at the bluff body face. Effects of air and liquid jet diameters and swirl of the annular jet on droplet size distributions are studied. Results indicate that the atomizer can be configured to control droplet sizes at the moderate gas−liquid ratios. A striking feature of the atomizer design is its sensitivity to small changes in diameters of liquid and air jets. Atomizer performance is especially sensitive to the air jet diameter. Sauter mean diameter varied by 55% to 128% for nearly 7% variation in air jet diameter. Imparting the swirl to the annular air jet is beneficial only if the air jet diameters are small.
