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: 0.7 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: 0.7 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: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RESUMO

The intense reaction observed between aluminum and oxygen in a liquid oxygen (LOX) environment has been termed a violent energy release (VER) reaction, but the details of the combustion process are not fully understood. In this study, the promoted ignition, flame spreading, and combustion phenomena of aluminum 3003 alloy tubing filled with LOX, surrounded by a shell of gaseous oxygen (GOX), were observed. Parameters that were systematically varied include the tube- and shell-side GOX and LOX pressures, flow rates, oxygen purities, as well as igniter location, tube-side GOX quality, and sample thickness. An extremely high flame spreading rate, a high luminosity flame-zone, and a very rapid rate of heat release characterize the VER burning mode. The effect of tube- or shell-side impurity is to raise the threshold pressure for self-sustained combustion and VER transition. Decreased wall thickness tends to lower the threshold pressure for self-sustained combustion and transition to VER. It is believed that the VER flame-spreading mode is primarily a result of high convective mass flux of oxygen into the reaction zone due to oxygen phase transition; this process greatly enhances both the reaction rate and the molten material removal rate.
