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

SINOPSIS

In this paper, a high-resolution visualization technique has been used in order to characterize Diesel spray structure in the near-nozzle field. For this purpose, three conical nozzles with different diameters have been used to relate nozzle geometry and spray behavior in non-cavitating conditions. As a first step, geometrical and hydraulic characterization of the nozzles has been performed. The analysis of the images obtained has shown that spray aperture varied significantly during the first millimeters of the spray, until reaching to the stabilized value of spray cone angle, which is the one usually characterized by other visualization techniques. Furthermore, the structure of the liquid−gas interface presented an oscillatory behavior, which is related to primary atomization process. These oscillations have been quantified and statistically correlated with nozzle geometry and operating conditions by means of three different non-dimensional numbers: Reynolds number, air/fuel density ratio, and Ohnesorge number.
