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

The present paper deals with numerical modelling of electric arc stabilized by water vortex. Two-dimensional axisymmetric model includes the arc discharge area between the cathode and the outlet nozzle of the water plasma torch. Thermal, electrical and fluid-dynamic characteristics as well as power losses of such arc has been studied for the range of currents 150-600 A and three different radiation models (net emission coefficient, net emission approach with reabsorption, partial characteristics). It was proved that the amount of energy losses transferred radially from the arc by conduction and radiation range between 70 and 35 % of the input power. Temperature and velocity fields within the discharge are close to each other for the partial characteristics model and for the net emission model with zero reabsorption of radiation. Calculations carried out by the partial characteristics method showed that reabsorption of radiation in arc fringes reaches about 26 % for the studied range of currents.
