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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRAKT

Atomization of a molten metal for metal powder production, spray forming or coating applications usually is achieved by means of two-fluid atomization with inert gas. In spray forming, which is a process for production of pre-shaped metal forms with excellent material properties, and sometimes in metal powder production, the type of atomizer used is a "free-fall" atomizer configuration.
Modeling and description of the melt disintegration process as the first unit operation of spray forming is of great importance and needs primarily informations about the gas flow field in the nozzle vicinity and the influence of nozzle configuration and operation parameters on the resulting spray.
This investigation analyses the transonic flow field of interacting gas jets and the nozzle flow field by means of experimental and simulation methods. Special attention is paid to the gas exit conditions at the atomizer and the configuration and arrangement of the gas jets. Results will illustrate the gas behavior in the free fall nozzle configuration and the potential of nozzle optimizations.
