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

RESUMO

To examine the effect of sonic and supersonic gas jets on twin-fluid atomization, a comparative study has been done for two different types of atomizers, using (1) an underexpanded sonic nitrogen gas jet from a converging nozzle (SN type), and (2) an overexpanded supersonic nitrogen gas jet from a converging-diverging nozzle (CD type, with an area ratio of 3). Water is used as the atomized liquid injected through a center orifice. The Malvern diffraction sizer measured the spray Sauter mean diameter (SMD) distributions on a line-of-sight basis and a tomographic transformation of the data found the radial distribution of drop SMDs. A Buckingham-PI dimensional analysis provided an experimental correlation of the spray SMD with the radial and axial location, liquid mass flux, and the gas jet stagnation pressure. The SMD correlation showed small distinctions (approximately 7.5%) between the two different nozzle types when other injection conditions remained fixed. The stagnation pressure showed a dominance over the nozzle configuration (SN or CD type) in determining atomization. Also, a modified energy model analysis provided a single correlation for spatially averaged SMDs for both SN- and CD-type nozzles. The stagnation pressure again played a dominant role when correlating the spatially averaged drop SMDs.
