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

RÉSUMÉ

Measurements of species, temperature, and their gradients are necessary for accurate modeling of solid propellant reaction mechanisms and their effect on the combustion characteristics of the propellant. The very difficult experimental problems posed by solid propellant combustion environments challenge even the most modern diagnostic techniques. CARS (coherent anti-Stokes Raman scattering) and DFWM (degenerate four-wave mixing) are coherent nonlinear, laser-based, optical diagnostics with high spatial and temporal resolution that accommodate well to the high interference and restricted optical access environments typical of solid propellant combustion experiments. CARS measurements at our laboratory have confirmed the equilibrium chemistry (temperature and species concentration) of nitramine propellant formulations burning at elevated pressures. A 1-D imaging configuration, realized with cylindrical optics and a 2-D detector, provides enhanced spatial resolution and single-shot data on species and temperature gradients adjacent to the strand surface during high pressure combustion. An experimental program, currently underway to obtain CARS and DFWM measurements near the surface of combusting energetic materials at atmospheric pressure using a motorized strand burner, will also be described.
