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

Based on the linear approximation of liquid constitutive equation, this paper investigated the instability and breakup of an annular power-law liquid jet into bounded and compressible gas medium, with both para-sinuous mode and para-various mode disturbances. The influences of gas−liquid velocity difference, Mach number, outer gas confinement, and gas−liquid density ratio were studied in detail. Numerical results show that with the increase of gas−liquid velocity difference, the jet instability is gradually dominated by the Kelvin−Helmholtz wave. The annular jet of power-law fluids in the bounded gas stream is more unstable than that in the open gas medium. As the gas velocity increases, the gas confinement has less impact on the jet instability. The gas compressibility can effectively destabilize the annular jet of power-law fluids and decrease the breakup scale. In low-speed gas stream, the jet breakup is mainly dominated by the para-sinuous mode. With the increase of the gas density and velocity as well as the Mach number, the para-varicose mode also exerts a significant effect on the breakup of power-law liquid jets. Especially in the cases of large Mach number and high gas velocity, either disturbance mode has the potential to dominate the breakup of power-law liquid jets.
