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

An experiment consisting of a polydisperse population of glass spheres, with a mean diameter of 30 μm, falling through the shear layer of a developing plane turbulent jet is reported. The aim is to provide robust data to validate existing and future Eulerian models of multiphase flow. The Reynolds number of the flow is ≈ 20,000, and the mean diameter of the glass particles coupled with the integral scale of this flow result in a Stokes number of 1. The measurement locations are within regions of two-way coupled flow. The measurements were obtained using laser and phase Doppler anemometry, and large sample counts were employed to ensure good statistical accuracy of higher-order moments. Single phase measurements reveal the turbulence characteristics are similar to other published work. An assessment is made of the conservation properties of the particle phase, which reveals the accuracy of the mass flux distribution to be typical of the phase Doppler anemometry method. The results show that the particle plume is "winnowed", and this permits the analysis of interphase transfer terms specific to different diameter distributions, to assess the accuracy of approximations published elsewhere. It is found that the accuracy of mean interphase transfer estimates, averaged over all particle diameters, provides poor accuracy, and some cases incorrect direction as well as magnitude.
