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

SINOPSIS

The combustion of AP/HTPB solid propellant sandwiches is investigated experimentally using ultraviolet (310±5 nm) chemiluminescent emission imaging and theoretically using Shvab-Zeldovich theory with finite Peclet number (Pe). Experimentally a thin binder lamina (50−300 μm) is sandwiched between two thick (∼ 1.5 mm) pressed AP layers, forming two AP/binder interfaces. Both pure and oxygenated binders (loaded with fine AP) are considered. Variations in Peclet number and stoichiometry are achieved through varying binder thickness and fine-AP loading. Both experimental and theoretical results show that fine-AP loading has a pronounced effect on the UV-active diffusion flame structure. For the same approximate binder thickness and Pe, adding fine-AP to the binder causes the observed flame intensity and height to decrease and the leading edge of the diffusion flame to shift from the AP region toward the AP/binder interface, in accordance with Shvab-Zeldovich mixing theory. Peclet number also affects diffusion flame structure in a predictable manner for both pure and oxygenated binders: increasing Pe increases the size and intensity of the UV-active diffusion flame.
