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

Studies of internal flow and discharged liquid jets from the nozzle are sometimes carried out under steady injection conditions. Although steady injection data can be helpful for the study of internal flow in the nozzle, fuel injection is carried out under a transient injection scheme, which gives in-nozzle cavitation phenomena a transient characteristic. This difference raises some questions regarding the applicability of steady injection data to the transient injection process. In this study, high-speed visualization of cavitation in a rectangular plain-orifice nozzle and discharged liquid jet was carried out under steady and transient injection conditions in order to examine the applicability of steady injection data to the transient injection process. The cavitation length and discharged liquid jet angle data from the transient injection is used to investigate transient cavitation development in the macro scale, while X-ray phase contrast imaging of in-nozzle cavitation was carried out to clarify the morphology of cavitation inception in the micro scale. From the study, we clarified the applicability of steady injection data to transient injection processes. Correlations obtained from steady injection data can be used to predict cavitation growth and the discharged liquid jet angle during the transient injection process where the duration of the flow rate increase is much longer than the time scale of flow development in the nozzle. High-speed X-ray phase contrast imaging revealed two kinds of heterogeneous nucleation processes of cavitation inception induced by bubble nuclei in the bulk flow or the nozzle wall surface. Both are governed by the turbulent flow structure in the nozzle.
