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

Краткое описание

A one-dimensional transient model of the combustion of energetic material (EM) with surface evaporation is formulated. The model considers heat propagation and EM condensed phase decomposition via a 1st order reaction. In the gas phase, it considers heat propagation, species diffusion, exothermic decomposition of vapor via a 1st order reaction and exothermic conversion of gas components via a 2nd order reaction. The matching condition at the surface corresponds to equilibrium evaporation in the form of the Clausius-Clapeyron equation. An external radiant flux is assumed to be absorbed in the bulk of EM and not to be absorbed in the gas phase. When simulating radiative ignition, it has been revealed that it can occur in one-, two- or three-stages. First, under irradiation, the evaporation and exothermic reaction in the condensed phase is initiated with a gas flame being formed far from the burning surface. The conductive heat flux from the gas to the EM surface is vanishingly small and the low rate gasification regime is realized. If the radiant flux gradually decreases up to zero, the flame approaches the EM surface and the heat feedback from the gas phase increases several times. A sustaining combustion is governed by heat feedback from the gas flame with burning rate several times higher than the gasification rate. Numerical experiments performed with the combustion model under study have revealed the intrinsic instability of steady-state combustion in case of EM with the rate controlling zone in the condensed phase.
