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

RÉSUMÉ

This study focused on scale effects on the in-nozzle flow regimes based on different scaled-up diesel injector nozzles, and the influences of the various flow regimes on spray characteristics. Optical results showed that flow regimes inside three different sizes of diesel nozzles went through single-phase flow, cavitation inception, cavitation shedding, wake cavitation, air suction, super cavitation, and hydraulic flip flow. Then the flow regime transition characteristics in three nozzles were analyzed. Cavitation inception number (K) in these nozzles were not the same because of the scale effect. Mean-while, the average cavitation shedding frequency decreased with the increasing of the scaling factor of the nozzle, but the modified Strouhal number (St) was almost the same. Moreover, the decrease of the cavitation number (K) caused the reduction of the average frequencies of cavitation shedding and air suction. In addition, the length of cavitation region showed a strong inverse correlation with the length of air suction region. The collapse of air suction, which was mixed with the cavitation or was pushed out the orifice rapidly, significantly influenced the spray cone angle. The characteristics of various flow regimes in different scaled-up diesel injector nozzles were analyzed in this study, which provided preliminary exploration to the in-nozzle flow characteristics from the scaled-up transparent diesel nozzles to real diesel nozzles.
