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

In spray painting and coating industries, air-blast injectors configured with a liquid-centered and two-stage gas nozzle have many advantages, including low paint bounce-back and high transfer efficiency. Experimental investigations are used to study overspray characteristics and transfer efficiency. To verify the effect of the gas jets, air-blast injectors with a gas post of two stages are designed to analyze the overall spray characteristics as well as to increase the transfer efficiency. The experimental results show that the liquid jet breakup is governed by the gas jets of the inner stage In the case of the inner stage gas injection mode, better atomization qualities can be achieved. However, in the case of the outer stage gas injection mode, larger droplet distributions appeared at the same measurement point. As the momentum ratio of the gas jets increased, the droplet sizes decreased. Additionally, the gas jets of the outer stage also contributed to the atomization at the far-field spray region, and it also contributed to the droplet transportation to the object. It was observed that, as the velocity of the gas jets increased, the mean drop diameters decreased and the transfer efficiency increased due to the outer gas post which caused an air curtain to surround the spray jets so that an impinged droplet could not overspray to the outer region of the spray jets.
