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 aim of this research is to develop a new hybrid breakup model by considering the influence of turbulence inside the nozzle and modifying the second breakup model. The model distinguishes between primary breakup and secondary breakup. In modeling primary breakup, the turbulence perturbation was characterized by the turbulence characteristic length and time scales, and the weight coefficient was used when incorporating into the primary breakup model (KH). For secondary breakup, a competition between the Kelvin–Helmholtz (KH) and Rayleigh–Taylor (RT) breakup mechanisms was adopted. In addition to the two breakup mechanisms above, the Taylor analogy breakup (TAB) was also selected as a third competing mechanism in this process. The modified FVM (finite volume method) method was used to solve fluid-flow equations and numerical simulations were performed with the in-house software GTEA (General Transport Equation Analysis). Four breakup models including the TAB, cascade atomization and drop breakup (CAB), Kelvin–Helmholtz Rayleigh–Taylor (KH-RT) and the new hybrid breakup (hybrid) were implemented in GTEA software. In order to validate the new hybrid model, comparisons of the predictions from the present model with experimental data and predictions from the other three models were conducted. The results indicate that prediction from the new hybrid model gives better agreement with experimental measurements than those of the previous model.
