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

This paper is devoted to the theoretical analysis of laminar axisymmetric boron particle-laden nonpremixed with oxidizer jet burning. An estimation of the combustion zone width scale shows, that for diffusion burning boron particles in rather wide range of dust fuel mass concentration and particle diameter the infinitely thin reaction zone approach is acceptable. Thus, the present theoretical model for laminar diffusion dust flame (LDDF) is, in general, analogous to Burke-Schumann's model. The calculations have been carried out in suppositions that the final combustion product is BO2 and the flame-sheet temperature is equal to the adiabatic burning temperature of the stoichiometric mixture of dispersed fuel and gaseous oxidizer. The calculated dependence of the flame height as function of boron mass concentration is essentially more weak than the directly proportional one following from quasy-stationary analysis. At the same time, the dependence of LDDF height as function of oxygen mass fraction in oxidizing gas is usual for diffusion combustion. The range of possibility of boron self-supporting LDDF realization is determined.
