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: 0.4 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: 0.00005 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: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRACT

One of the most widespread areas of plasma technology is a treatment of fine-dispersed materials in plasma jets. Complexity of an experimental research of system "plasma flow - particles" has caused the creation of the mathematical models describing movement, heat transfer and physical and chemical transformations of dispersed materials in plasma. Researches of heat transfer in high-temperature flows are of significant interest as heat transfer from plasma to particles of powder is the determining factor.
A number of studies of particle heat transfer in thermal plasmas give the following expression for Nusselt number: Nu=2+A·Re0.5·Pr0.33, where A is constant. However, this expression overestimates Nu in comparison with experimental data. In this connection authors offer the criterial expression for calculation of particle heat transfer in plasma taking into account the correction for conductive term: Nu=2·(Vs/Vp)+A·Re0.5·Pr0.33. Introduction of correction namely Vs/Vp obviously explains mechanism of influence of heat transfer conductive component on particle conductive-convective heat transfer in thermal plasma and result in sufficiently good agreement of calculations with numerous experimental data.
