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

Краткое описание

The near-nozzle, global, spatial, and temporal characteristics of a hollow-cone spray produced by a pressure swirl-type atomizer have been investigated experimentally. Particular attention is given to the transient phase just after needle opening, which, for pulsed or intermittent atomizers, plays an all-important role in defining the global spray behavior and, more significantly, atomization quality. Qualitative and quantitative spray measurements have been achieved via the combined diagnostic techniques of high-magnification charge-coupled device (CCD) imaging and phase Doppler anemometry (PDA), which provides useful data not only in terms of improving the design and performance of pressure swirl atomizers, but also for the validation and refinement of numerical spray models. High-magnification CCD images of the intact near-nozzle liquid sheet reveal a certain degree of helical swirl motion, although laser Doppler velocimetry (LDV) results indicate that the tangential swirl motion imparted on the liquid sheet decays rapidly within the first few millimeters of the atomizer orifice to near-negligible levels. Images of the poorly atomized “preswirl spray” formed during the early transient phase of injection also revealed the presence of large, nonspherical liquid masses up to 1 mm in size, even as far as 72 nozzle diameters downstream. The spray-induced gas phase flow, which results in the characteristic toroidal vortex, was found to have a significant influence on droplet trajectories and segregation of the fast-moving large (D32 between 25 and 30 μm) and small (1−5 μm) droplets within the spray. Estimates of characteristic droplet Weber numbers have also been made, which, in general, were found to be less than the critical values required for secondary droplet breakup to occur.
