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

Краткое описание

Numerical simulations of the fully developed flow region in a cylindrical channel of the plasmatron are performed. As the results, temperature and velocity radial distributions, dependences of pressure and voltage gradients on operating parameters of the plasma torch are obtained for the argon arc burning in the laminar gas flow. Special attention was given to define and to calculate criteria for transition from the laminar to the turbulent regime of the gas flow in the fully developed flow region. For this purpose some experimental results of Frind, Damsky [2] and Runstadler [1] were employed. Using these experimental results we have calculated the value of the critical Reynolds number characterizing the onset of the turbulence for the arc flow.
