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 paper studies the structure of ammonium dinitramide (ADN) flame at 4.0 MPa using a probing mass-spectrometry, microthermocouples and modeling. Strands were burnt in a high-pressure combustion chamber in argon atmosphere. To withdraw sample from the field of high pressure and temperature a probe of stainless steel was used (an outlet orifice 170 μm in diameter, internal expansion angle of 40 deg). The temperature profiles were obtained using Pt-PtRh(10%) Π-shaped thermocouples 20 and 50 μm in diameter. Concentration profiles of the main species N2, O2, NO, N2O have been measured. Three main temperature zones have been determined or observed. In the first narrow (0.1 mm wide) low temperature zone nearby the burning surface the temperature raised from 640K to 970K. In the second zone about 1 mm wide the temperature raised from ∼970K to 1370K. At the distance more than 1 mm from the burning surface the third wide zone about 3−6 mm wide was found, where N2O is consumed and temperature further raised from ∼1370K to 1770K. The dependency of this zone width on ADN burning rate was found. The obtained experimental data (the combustion products composition and temperature) were used as boundary conditions for modeling the structure of ADN flame zone at 4.0 MPa using CHEMKIN Code. A mechanism incorporating 170 reactions for 29 species has been used for calculations. A satisfactory agreement of the experimental and calculation data is obtained.
