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

The method of direct numerical simulation of nano and conventional aluminum agglomeration in composite solid propellant combustion is developed. The method under consideration falls into three stages. In the first stage, a simulation of composite solid propellant structure is performed. An analysis of the propellant structure obtained in calculations is carried out. It is shown that the contacting aluminum particles form lengthy clusters in the propellant volume. The role of the clusters in aluminum agglomeration is discussed. In the second stage, the propellant combustion and aluminum heating in the propellant condensed phase are modeled. In the third stage of simulation, the evolution of aluminum particles above the propellant burning surface is considered. It is shown that the contacting aluminum particles form coral-like structures above the propellant burning surface. A simulation of the coral-like structures above the burning surface is carried out. The results of the numerical simulation are compared with the experimental data, obtained by high-speed digital recording of aluminized composite solid propellant combustion. A method for modeling the coral-like structure evolution under the action of gas-dynamical forces and adhesive forces between aluminum particles in the structure is suggested. Calculations of aluminum agglomeration were made. The results of calculation are dynamically represented and compared with the high-speed movies taken on combustion of composite solid propellants.
