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

ABSTRAKT

Department of Mechanical Engineering, University of Waterloo, Waterloo, Ontario, Canada This article reports the absolute and convective instability of an annular viscous liquid jet with its inner and outer surfaces exposed to inviscid gas streams of unequal velocities. The effects of geometric and various flow parameters are investigated. It is found that both absolute and convective instability exist for para-sinuous and -varicose modes under certain flow conditions. For para-sinuous mode, the annular liquid jet, with an inner gas moving at relatively small velocities, can have either convective or absolute instability, depending on specific flow conditions. However, the jet is of only absolute instability if the inner gas is stationary or moves at sufficiently large velocities. Para-sinuous unstable waves outgrow para-varicose waves and hence dominate the jet instability process, according to both absolute and convective instability analyses. The liquid viscosity has a stabilizing effect on the jet instability, but the gas inertial force shows a fairly complex influence on the absolute instability. The convective growth rates for various inner gas velocities indicate that not only the velocity difference between, but also the absolute velocity of the liquid and gas, determine the jet breakup process.
