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

As part of a research effort to develop comprehensive gas-phase reaction mechanisms for nitramine combustion, the present paper reports on recent sub-model development of H2/N2O kinetics. A single reaction mechanism, based on literature thermochemical and kinetic data and developed from intermediate temperature flow reactor studies, is tested against previous high temperature shock tube data, low temperature static bulb reactor data, and laminar premixed flame speed data. Model predictions are found to be in good agreement with the shock tube and flow reactor data, but too fast when compared against the bulb data. In addition, predicted flame speeds are found to be ∼ 15% lower than those measured experimentally. The present results further indicate the importance of the branching channels of the H + N2O reaction over the entire temperature range as well as secondary reactions involving NH, and suggest that, at high temperatures, the rate constant for the direct reaction of CO + N2O is lower than predicted from extrapolation of previous evaluations.
