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

要約

The aim of this article is to characterize the mean behavior of a polydisperse aerosol discharging streamwise into a homogeneous and nearly isotropic grid turbulence. Air-blast coaxial atomization was used to obtain a polydisperse aerosol composed of water droplets with diameters ranging from 5 to 200 μm, with a mean arithmetic size of about 40 μm. Properties of the dispersed phase, such as velocity, size distribution, size-velocity correlation, and number density, were measured by phase Doppler anemometry at several locations behind the grid in the developed jet region, beginning at 100 nozzle diameters downstream of the jet origin, where dilute spray conditions were encountered. The instrument was also used to evaluate the concentration profiles and to compare the mass flux evaluated at six explored stations to the initial flow rate at the nozzle. Further mean velocity profiles of the carrier airflow were obtained by pressure measurements. The mean behavior of the droplets is quantified in terms of mean Stokes numbers, and a turbulent Schmidt number is calculated for the mass and momentum transfer of the two-phase jet entrained by the turbulent co-flow. In the present case, the "dispersion" process appears to be controlled by the dominating inertial effects, and the larger droplets tend to accumulate on the outer edges of the jet.
