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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

The problem of predicting the characteristics of the spray produced by the disintegration of an attenuating liquid sheet emanated into a surrounding gas is considered. A second-order nonlinear perturbation analysis is employed to investigate the evolution of the instability waves that lead to sheet breakup. The sheet breakup length, thickness, and time as well as size of drops formed upon sheet fragmentation are estimated. It is found that the breakup length, breakup time, and drop size decrease as the Weber number is increased. The breakup thickness increases by raising the Weber number. An initial disturbance of larger amplitude induces faster sheet atomization and larger drops. A higher gas-to-liquid density ratio causes a shorter sheet breakup (intact) length and reduced resultant drop size associated with larger dominant wave numbers. The present theoretical predictions are compared to experimental data, and empirical correlations and favorable agreement is observed.
