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

要約

An experimental study of flame-spreading behavior over thin Mg/PTFE/Mg foils (called Enerfoil™ Pyrotechnic Film) with thicknesses of 10/25/10 μm was conducted in an argon environment. This thin film pyrotechnic material has been designed to serve as an ignition enhancer in passenger-side airbag gas generators. The objective of this study was to determine the effects of initial chamber pressure and gap width between two foils on the intrinsic flame-spreading rate of Enerfoil™ films. In the experimental setup, the steady-state flame-spreading rate (VFS) was deduced from the flame-front trajectory measured by an array of fast-response Lead-Selenide (Pb-Se) IR photodetectors. The initial chamber pressure was varied from 0.1 to 10.5 MPa. Results indicated that for single-foil tests VFS decreased as the initial chamber pressure was increased; this observed trend is believed to be caused by a greater heat loss to the ambient gas at higher pressures. An experimental correlation was developed with a pressure exponent of −0.118. For double-foil tests, the gap width between two adjacent foils was varied from 50 to 400 μm. It was found that for double-foil tests there exists an optimal gap width for obtaining a maximum VFS at a given initial chamber pressure. The optimal gap width appears to become smaller as the initial chamber pressure increases. For each gap width tested, there is also an optimal pressure at which the VFS reaches a maximum. The existence of the optimal pressure and gap width is caused by the combination of several factors, including required physical space for complete gas-phase reactions, heat transfer rates to both unburned foils and ambient gases.
