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

Краткое описание

A dual-mode linear analysis of temporal instability for the power-law liquid sheet moving into an inviscid gas stream is implemented to theoretically study the breakup of the sheet. Applying the linear instability theory, the dispersion equations are derived under the dual modes of antisymmetric and symmetric disturbances by linearizing the nonlinear power-law term based on some rational and necessary assumptions. The growth rate of the two disturbances and corresponding wave number are obtained by numerically solving the dispersion equations. The effects of thickness and velocity of the sheet, initial disturbance, surface tension, consistency index, flow behavior index, gas density, and gas velocity (relative velocity) on the instability of the power-law sheet are investigated. Furthermore, to evaluate the breakup time and breakup length of the sheet and the mass mean diameter of the droplets separating from the sheet, the dominant and neutral curves are plotted. Relative results indicate that the antisymmetric disturbance is the predominant mode in the instability with greater growth rate than the symmetric disturbance. The decreases of the surface tension coefficient and sheet thickness, or the increases of the sheet velocity, gas density, and relative velocity can accelerate the instability of the sheet bringing a better atomization. Enlarging consistency index and flow behavior index can resist the breakup of the sheet, but the influence will be unapparent when the two parameters exceed a certain value, respectively. Moreover, the initial disturbance dramatically just has a weak effect on the instability of the power-law sheet through linear analysis.
