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

The far-field turbulent structure of an airblast coaxial spray without swirl has been studied using a two-velocity-component phase Doppler anemometer. Size, velocity, and droplet number density have been measured at nine different locations from the injection plane. The measurements have been checked against an extinction sensor. Deceleration has been studied and compared with other experiments in coaxial sprays, gaseous, and particle-laden jets. An expression, valid to describe the deceleration in coaxial sprays with a similar breakup mechanism, is proposed. Furthermore, five representative droplet families discriminated by their Stokes number have been selected to study differences in their dynamic evolution in the spray. Self-similar velocity profiles in the mean and turbulent components have been obtained. In the axial component all droplets are seen to behave similarly, while significant differences are observed in the transverse velocity. Mean particle number density profiles are top-hat-shaped, while the highest number density of droplets with Stokes number near unity is placed at off-axis locations. The distribution of the volume flux has also been calculated.
