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 series of parametric computational studies are conducted to assess the frequency/wavelength of disturbances that issue into the atomizing jet as a result of instabilities in the vena contracta formed at the orifice entry. Axisymmetric, laminar incompressible computations are performed for a variety of orifice lengths and inlet rounding levels. The results are summarized and compared against classical linear theories. The computations show that as the inlet of the injector is rounded, the amplitude of the unsteadiness is reduced, and for large enough radii the unsteadiness is absent. Furthermore, as the injector length is increased, local maxima in the amplitude of the unsteadiness are observed. Finally, the results are compared with linear theory and it is hypothesized that the wavelengths associated with unsteadiness could be amplified by the boundary-layer instabilities at the exit of the nozzle and lead to the primary atomization of the liquid jet.
