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

Liquids or suspensions are dispersed into sprays of small droplets by atomization of two-phase gas-liquid mixtures. Thus narrow droplet diameter distributions and a high interface area density of the liquid phase are generated in order to increase heat and mass transfer. The mean droplet diameter of the spray is time dependent. It also depends on the total pressure upstream from the nozzle, the volumetric flow rates of the liquid and the gas phase, as well as on the flow regime inside the nozzle. The radial and axial profiles of the void fraction inside the nozzle are measured with an electrical measurement technique. In addition, the flow in the nozzle is visualized by a high-speed camera. Three flow regimes are identified. A model is established to predict the flow regime inside the atomizer. It turns out that the flow regime changes by accelerating the flow to critical conditions. The visualized flow fields are compared to calculated ones. A model to predict the breakup regime is established considering the phase distribution and the critical flow conditions at the exit cross section.
