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

A stratified two-phase gas-liquid flow confined in a channel is analyzed. Contrary to previous papers of the literature, where a parallel flow configuration is classically analyzed with a plug velocity profile in both fluids, in the present paper the flow is spatially developing, starting from a plug-plug profile at the channel entrance. The sudden change of interface boundary condition produces the flow development and the emergence of a single Kelvin-Helmholtz wave, whose formation and evolution are numerically studied. Numerical simulations are carried out by means of the volume of fluid (VOF) technique. The most physically relevant result is the nonlinear amplification of finite-amplitude entrance disturbances linked to the sudden change of inlet boundary condition, manifested as the formation and propagation of a single Kelvin-Helmholtz wave. In addition, a linear amplification of very small numerical artifacts, which arise around the interface region not yet reached by the traveling wave, is also discussed.
