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

The purpose of this paper is to summarize important aspects related to the study of the mathematical model of internal flow and the nominal performance main parameters of the conical swirl atomizer similar to that used in the JT8 Pratt & Whitney engine. The mathematical proposed model is composed of the inviscid fluid theory of Abramovich and incompressible friction theory of Kliachko, applied to the complexity of the geometry of the inlet channels, such as the irregular cross-section area and nontangential nature with respect to the swirl chamber (geometric characteristics of the conical swirl atomizer). Computational fluid dynamics (CFD) provides additional information on internal flow characteristics of swirl atomizers, the main difficulty of which is the precise control of liquid/air. It was found that by using the volume of fluid (VoF) method and k-epsilon turbulence model (implemented in software Fluent 6.3.26), an understanding of physical phenomena can be obtained as well as better visualization of the air core and hollow-cone spray angle of the atomizer, where the computational domain is composed for three-dimensional structured grids. Experimental data and numerical simulation were used for validation of this mathematical model. These results provide elementary and worthwhile information for the practical design of swirl atomizers, in addition to cost reduction before the combustion testing phase.
