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

SINOPSIS

The interphase momentum coupling and growth in interfacial mass flow rate corresponding to liquid jet injection into a quiescent gas are studied in the present work via highly-resolved simulations. It is shown that the spray formation process is composed of three regimes. In the first regime, which is closest to the nozzle, the surface of the jet undergoes interfacial perturbations and breakup; however, the internal liquid core remains intact, and the interphase momentum exchange is weak. In the second regime, primary atomization occurs, resulting in the breakup of the entire jet. Besides the creation of relatively large amounts of interfacial area, this second regime is characterized by a huge increase in the momentum coupling between the gas and liquid phases. In the last regime, both phases merge into a quasi-equilibrium state, where the atomization process is essentially complete, and both phasic velocities converge to a unique average value. In a subsequent analysis, this unique value is shown to be given by (UinjρLΩL)/ρLΩL+ ρGΩG ).
