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

The dispersion of a kerosene fuel spray generated by plain-jet-in-crossflow injection into the inner annulus of a counter-swirling double-annular air flow was investigated experimentally. Tests were conducted at 6 bar and 12 bar static air pressure and 750 K air temperature and at the corresponding cold test conditions in terms of air density, with an additional excursion to higher air density (9.3 bar at 290 K). The air flow was characterized by laser Doppler anemometry (LDA) and the spray dispersion was investigated by phase Doppler anemometry (PDA). It was found that the very small droplets generated at high pressure have such a great ability to follow the streamlines of the air flow that they remain trapped in the inner annulus, preventing the formation of a uniform fuel–air mixture in the annular flow. For an in-depth discussion of the results, the appropriate versions of the Stokes number are introduced and evaluated.
