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

An experimental study of a further development of a novel atomizing nozzle is presented. The novelty of the nozzle lies in the incorporation of a self-driven, hydraulic turbine, which provides improved atomization performance. The inclusion of this rotating component promotes smaller particle sizes within the plume for a given pressure and flow rate. A new version of the nozzle is described in terms of both design and performance. Previous versions of the nozzle produced spray plumes by a variety of atomization processes. This new version incorporates a series of enclosed spray channels that provide a spinning disk-type atomization effect. The effect on the spray plume is to produce a Sauter mean diameter that varies with fluid feed pressure and a plume spray density that is similar to a solid cone-type plume. The Sauter mean diameter was found to vary within the range of 80−190 μm. The observed droplet size distributions suggest that the nozzle produces a spray similar to that produced by spinning disk atomizers in the outer region of the spray plume. The volumetric concentration in the inner spray is reduced to 40% of that in the outer plume, and the droplets present in this region are smaller than in the outer plume.
