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

Краткое описание

A generalized formulation to characterize droplet size distributions in sprays is proposed. The methodology is based on the Pearson system of frequency curves and on experimental data from different liquid atomizers available in the open literature. The method demonstrated that droplet size distributions in sprays were restricted to the Pearson type I and type VI curves, respectively, called beta and beta prime distributions. It was also verified that the Pearson type III could be used as a simplified model for liquid atomization systems with accuracy comparable to the Nukiyama-Tanasawa distribution. Pearson type III is the so-called gamma distribution, and it is a transition curve between Pearson type I and type VI. As part of this study, random generation of initial droplet size distribution in the spray, following a beta distribution, was used as a boundary condition in the air-blast atomization model implemented in FLUENT® V.6.2.16, and the evolution of a spray produced by a commercial atomizer was evaluated. The nozzle used in the study was the airassist atomizer model BETE XAPR-200, which provides a solid-cone spray. For the simulations, the grid was generated with the meshing software Gambit® V.2.0.4. Very good agreement was obtained between experimental and numerical values.
