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

Determination of velocities and locations of liquid droplets formed during the atomization process of a liquid jet injected in a high-pressure air cross flow represents an essential step in the definition of appropriate boundary conditions for the elaboration and validation of reliable numerical models. In this paper, three test cases relative to different air-to-liquid velocity ratios and air temperatures are analyzed by means of elastic scattering imaging and particle image velocimetry (PIV). The significance of the PIV measurements, evaluated as a function of spatial position and operating conditions, was adequately high with the exception of the nearest field to the injection point, where the spray is too dense. Velocity data, measured in the axial and transversal planes, are presented along with corresponding velocity components' profiles at selected positions. Results show the rapid alignment of droplet trajectories to the airflow and the dominant role played by the airflow in determining final droplet velocities and, hence, their placement in the spray plume. The droplets close to the windward profile move parallel to the jet leading edge, whereas in the leeward region they cross the scattering intensities' isocontours. On the grounds of these results, a synthetic description of liquid droplet velocities' behavior in the different regions of the spray plume is given that represents a useful conceptual tool in the attempt to correlate physical mechanisms, underpinning atomization processes, to the observed phenomenologies.
