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

In the present paper, the laws of sequential distribution of the parameters of nonstationary two-dimensional flows of the mixture of pelletized solid propellant (PSP) combustion products (CP) along the gas generator (GG) cavity is investigated numerically. For imitation of the exploitation conditions the GG is placed in a cylindrical imitation chamber. Two-dimensional gas-dynamic equations of motion of the CP mixture between the granulated elements (GE), are written in the axisymmetrical statement for the multicomponents biphase mixture of ideal gases. A peculiarity of the model is that the physical processes accompanying the CP filtration through granular propellant are taken into account. Calculation of the solid phase temperature state and its non-stationary burning-out is carried out on the method, made up in accordance with the model of Prof. R. Ye. Sorkin of Russia. The heat problem is solved in each of gas-dynamics knots for a separately taken propellant pellet. The equations, describing the gas-dynamic processes, are solved numerically by the Large Particles Method, developed by Prof. Yu. M. Davydov of Russia, with using of a number of modifications. For the complex check-up of the developed mathematical model of physico-chemical processes, the numerical calculation results have been compared with the fire stand tests. The analysis of results of numerical investigations of laws of the physico-chemical processes evolution in the GG reveals that the flows patterns in the GG cavities are characterized by substantial inhomogeneity, increasing as the process develops and expressed temperature sensitivity. After the pelletized propellant complete ignition, the flow non-one-dimensionity degenerates gradually and parameters in the GG volume can be averaged. Using of two-dimensional gas-dynamic model opens a possibility for obtaining the information on processes proceeding in the GG at a new qualitative level, gives a more comprehensive idea about the physico-chemical processes essence and permits to abandon the use of a number of empirical relations.
