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

RESUMO

The characteristics of gas-centered swirl coaxial (GCSC) injectors used in a staged-combustion cycle of Russian liquid-rocket engines were investigated. This study determined how the spray characteristics of GCSC injectors are influenced by the momentum flux ratio, gap thickness, and recess length used as important coaxial injector parameters. The film thickness and spray angle were measured by the electrical conductance and backlight image methods, respectively. The liquid film thickness and spray angle were changed according to the spray condition. The spray characteristics at low liquid pressure drop were sensitive to gas but not at high liquid pressure drop. The momentum flux ratio showed a better relationship with spray characteristics than the spray condition of liquid and gas, respectively. As the momentum flux ratio increased, the spray characteristics tended to decrease overall and this tendency occurred at a lower momentum flux ratio as the recess ratio increased. Also, the spray characteristics varied with the gap thickness. The liquid film thickness and spray angle were relatively low in small gaps, and were similar as the gap thickness increased.
