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

摘要

The linear temporal and spatial−temporal instability behavior of a confined swirling annular liquid layer was investigated theoretically. The practical situation that motivated this investigation is the core-annular film flow regime encountered in industrial heat transfer and the recessed gas-centered swirl coaxial injector, usually used in liquid propellant rocket engines. The dispersion relation for the liquid layer was developed and a parametric study was performed using this relation on the temporal and spatial−temporal instability to test the influence of non-dimensional flow parameters on the stability behavior of the layer. The temporal stability analysis shows that a larger non-dimensional outer injector radius, Rossby number, and liquid Weber number would destabilize the confined annular liquid layer. A larger liquid-to-gas density ratio and velocity ratio would decrease the disturbance growth rate. In the spatial−temporal mode, the absolute growth rate can be affected by these parameters. For a small value of liquid-to-gas density ratio, velocity ratio, and liquid Weber number, or a great value of non-dimensional radius of confinement wall and Rossby number, the flow is absolutely unstable. The wavelength predicted with spatial−temporal analysis is much larger than that predicted using the temporal analysis. However, the wavelength rarely changes with these dimensionless parameters in absolute instability mode.
