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

Free-fall gas atomizers are often used for liquid solution and melt atomization in the area of powder production and spray forming applications. This external mixing atomizer often uses two separate gas nozzle systems, namely, a primary gas nozzle (for prevention of major gas recirculation flow in the atomization area) and a secondary gas nozzle (for atomization), both concentrically surrounding the central liquid jet. Due to this specific arrangement, the atomization area is separated from the atomizer body, however the primary and secondary gas pressures need to be carefully adjusted. To improve the free-fall atomizer construction and operating conditions, the gas flow field of a conventional free-fall atomizer was investigated by numerical simulations. Aim of the investigation was to economize the primary gas application, while safely operating the atomizer without recirculations. Advantages of the derived flow-adapted atomizer design are a reduction in gas consumption, as well as the potential of generation of smaller particles. This effect was proven by atomization of a viscous melt.
