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

SINOPSIS

This study identifies the characteristics of a gas-centered liquid annular sheet in order to focus on the instabilities of the spray. To characterize the spray oscillation of the gas-centered liquid annular sheet, two measurement methods were used. Indirect photography was used to measure the instability wavelength and to distinguish the instability mode of the liquid sheet, and laser diagnostics were used to measure the frequency of the instability. In this study, three instability modes were observed, each mode had a different spray structure, and the instability characteristics of each were analyzed. As the gas-liquid momentum ratio increased, the wavelength of the spray oscillation decreased and the frequency increased. With an increase of the recess ratio, the wavelength increases and the frequency decreases. Consequently, it was clear that both the gas-liquid momentum ratio and the recess ratio can affect liquid sheet instability. The instability transition map can be obtained. The instability mode of the spray oscillation by normalized wavelength was identified.
