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

ABSTRAKT

A rotating spray faint atomizer consists of a spinning cup from which paint droplets are ejected. Around the periphery of this disk, an axial air flow blows these liquid particles, which are projected against the surface to be painted. Under some particular circumstances which occur in industry, this axial air flow may be stopped and, owing to the Coanda effect, the radial flow of paint may be attracted backwards in the direction of the atomizer itself. This "reverse flow effect" is detrimental to industrial performance, and it is the purpose of this work to consider the possibility of predicting and even preventing this phenomenon. Using computational software, a simplified model of an atomizer is first considered and the illustration of the reverse flow effect is shown. In the second part, a full numerical modeling of a real geometry is treated and a solution is suggested to improve the performances of this type of equipment. Recommendations are given for an optimal design which prevents the reverse flow effect in a rotating atomizer. For a given air flow rate, it is shown that the highest output momentum of the jet flow should be obtained.
