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

RÉSUMÉ

A temporal stability analysis has been carried out to model the breakup of a power-law liquid jet. The dispersion relation of a power-law liquid jet is obtained by integrating the axisymmetric governing equations for the power-law liquid jet. The effects of the surface tension, liquid jet radius, air boundary layer, liquid consistency coefficients, gas dynamic viscosity, power-law index, and the relative velocity between the liquid and gas phase on the maximum growth rate and the dominant wave number are studied. The investigation shows that the maximum growth rate and the dominant wave number increase with the increase of the relative velocity and gas dynamic viscosity, while they both decrease as the liquid surface tension, liquid jet radius, air boundary layer, and power-law index increase. Therefore, increasing the relative velocity and gas dynamic viscosity, or decreasing the liquid surface tension, liquid jet radius, air boundary layer, liquid consistency coefficient, or power-law index will improve the instability of the liquid jet and be advantageous for the breakup of the liquid jet. The liquid consistency coefficient on liquid jet instability has a critical value, and the low liquid consistency coefficient will make the jet more unstable.
