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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

Spray trajectories of liquid jets injected into a subsonic crossflow were experimentally studied and correlated with jet operating parameters. The spray dynamics are known to be different in the three spray regimes: the column, the ligament, and the droplet regimes. Trajectory correlations were therefore developed for the column and droplet regimes separately in an effort to gain a better understanding of the flow dynamics. A previously obtained column trajectory correlation was tested against results from other studies; the comparison indicates that the trajectory can be predicted based on consideration of aerodynamic acceleration. However, the trajectory may be affected by variations in incoming air velocity profiles, boundary layer thickness, and injector passage design. Experimentally obtained spray trajectories were correlated using simplified momentum equations of a spherical droplet in an air flow. Correlations of droplet locations, velocities, and drag functions at the upper spray boundary were obtained. Results suggest that droplet sizes decrease as the air freestream velocity increases, and they are independent of liquid property variations. At x/d = 150, the droplets at the upper spray boundary always have an axial velocity of 70% of the air freestream velocity and a transverse velocity of 51 % of the injection velocity. Predictions based on the correlations obtained are in fair agreement with measured values. The correlations obtained in this study provide not only the location of the spray boundary, but also droplet sizes and velocities.
