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

SINOPSIS

In internal-mixing twin-fluid atomizers the liquid is entrained by an air flow of comparatively low velocity. When passing the orifice of the atomizer the gas and the liquid are accelerated simultaneously and the liquid is atomized when the Weber number We increases up to a certain limit. Experiments with single drops show that both the geometry of the nozzle and the viscosity of the liquid influence the onset of the liquid breakup and the Sauter mean diameter D32 of the secondary spray. This influence on both the onset of liquid breakup and the characteristic D32 of the spray has been recognized even for low Ohnesorge numbers On < 0.01. An optimum Ohnesorge number has been found for which the bag breakup occurs for lowest Weber numbers and the Sauter mean diameter of the secondary droplets becomes minimum. Within the range examined, the Sauter mean diameter reaches a minimum for We < 40 and only insignificantly increases at Weber numbers up to We Ј 250.
