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

RÉSUMÉ

Twin-fluid atomization by means of free-fall atomizers is a common process technology in metal powder production and especially in metal spray forming. The latter is a process route for producing near-net-shaped preforms with excellent material properties. Here, disintegration of the molten metal results in a characteristic particle size, momentum, and thermal energy distribution in the spray, which strongly affects the behavior and efficiency of the spray forming process. The gas nozzle arrangement in the free-fall atomizer consists in most applications of a number of discrete jets. Spreading and interaction of the individual gas jets result in a characteristic transsonic gas flow field in the vicinity of the atomization area. Changes in the gas momentum distribution in the atomization area are discussed, dependent on the geometric arrangement of the jets and the formation of the gas nozzle contours (converging or converging/diverging). The particle size distribution in the spray is analyzed for a model fluid and a metal melt. Some design criteria for free-fall atomizer nozzle arrangements with efficient liquid metal atomization are given.
