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

ABSTRACT

Based on the use of special propellants that generate model monodisperse agglomerates with given size and structure during combustion, a new approach has been elaborated for reducing the uncertainty in data obtained on agglomerate evolution. The experiments with agglomerates of 400−540 μm in size and initial aluminum content 42.6 % were carried out under pressures 10−64 atm. Via direct size and weight measurements and chemical analyses of sampled particles, the following correlation for incompleteness of aluminum combustion (η) has been found: η = 2.86t−0.28P−0.20, where η = mAl/mAl0; mAl is the mass of free aluminum in sampled agglomerate and mAl0 is the initial mass of aluminum in agglomerate; t is the residence time for agglomerate in flame of burning sample (20<t<90 ms); P is the pressure (10<P<64 atm). The mass fraction (φ) of oxide accumulated on the burning agglomerate was found to increase with extent of aluminum conversion ξ = 1−η as ξ = 0.539 + 0.213ξ. The agglomerate mass also increases with ξ due to oxide accumulation on the burning agglomerate. For calculation of 1) the burning agglomerate motion law and 2) the residence time for agglomerate in the flame, the drag coefficient Cd was assumed in the form Cd = K/Re, where Re is the Reynolds number. K was determined in special experiments on panicle trajectory visualization at pressure 1 atm and found to be equal to K = 45±7 for 7<Re<9.
