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

SINOPSIS

The purpose of this study is to clarify the breakup mechanism of a high speed liquid jet, by investigating the mutual relationship between the internal flow in the nozzle hole and the disintegration behavior of the liquid jet. In order to clarify the effects of the internal flow in the nozzle hole on the spray characteristics, experiments wane performed under conditions ranging from atmospheric to high ambient pressures, by using transparent nozzles with various length-to-diameter ratios of the nozzle hole L/D and the inlet shapes of the nozzle hole. The behaviors of the internal flow in the nozzle hole and the disintegration behavior of the liquid jets were observed by the photographic technique. Moreover, the vibration accelerations associated with disturbances in the nozzle hole were measured using a piezoelectric acceleration transducer, in order to quantify the magnitude of the disturbance of the liquid flow in the nozzle hole. It was shown that the vibration acceleration level VAL was proportional to the magnitude of the disturbance in the nozzle hole. As a consequence of this study, it has been determined that the important factor in the breakup processes of the liquid jet was the disturbance of the liquid flow due to cavitation phenomena.
