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

This paper models the breakup of a circular jet, which is subjected to both pure and composite distur-bances using an interface tracking method. The tracking method referred to as the Level-Set Method (LSM), numerically simulates disturbance growth under the same conditions as those in experiments previously published on jet breakup using a piezoelectric actuator. Results from the modeling are com-pared with the experimental results. Experimentally, the jet is modulated through the axial vibration of an orifice plate. In the model, the axial disturbance is an artificially applied velocity fluctuation at the inlet. Both modeling results and experimental observations of the breakup due to a pure disturbance clearly show formation of large satellites between main droplets at lower frequencies inside the regular breakup regime. Previous experiments showed that practical devices always show generation of interfering disturbances along with the fundamental disturbance, which can have different impacts on the jet breakup. Experimental results are compared with simulation examples studying breakup due to a composite disturbance. Comparison shows that the model clearly accommodates a composite disturbance and it accurately predicts results similar to those seen in experiments. Previous experimental investigations also proposed a composite disturbance as the solution to merge satellites or decrease their size. Although it is practically not possible to measure the actual amplitude magnitude in experiments, the model demonstrates key features and qualitatively shows how the breakup is affected by adding a high frequency mode.
