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: 1.3 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: 1.7 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: 0.7 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: 0.00023 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: 0.11 SJR: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

摘要

Macroflows are considered for simulation of hot gas flow in a channel with nanopores. The flows are caused by the effects of gas slip, jumps of temperature and concentrations of gas mixture components on the surface of pores. The macroflows are obtained by averaging microflows in nanopores. The intensities of slip processes and jumps of temperature and concentrations are presented in dimensionless variables as functions of porosity, coefficients of gas molecules reflection from the surface of pores, and coefficients of thermal and concentration accommodation. Heat and mass transfer is calculated at various intensities of slip processes and jumps of temperature and concentrations. The model developed is applied to synthesis of magnesium−zinc and nickel−zinc ferrite nanoparticles. The results are compared with the experimental data. The model uses the experimentally determined activation energy and ignition temperature, the slip parameters and jumps of temperature and concentrations of gas phase components on the surface of pores at high Knudsen numbers. The results of calculation agree satisfactorily with the measured values of temperature. The theoretical model allows predicting the characteristics of the combustion wave at both large and small porosity of the sample in the case of surface combustion.
