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

This paper describes quantitative numerical investigations of turbulence and arc interaction carried out in our laboratories in the frame of industrial applications such as electric arc furnaces and high voltage circuit breakers. The capabilities of k-epsilon models to account for the laminarization process due to large variations of the viscosity is studied in two dimensional axisymetrical stationary simulations of arc flow. A first attempt at modelling the effects of turbulent fluctuations on electrical source terms is also presented. A second order closure model has been used in order to improve the turbulent flux predictions by taking into account the large anisotropy of the turbulent motion. The second part of this paper is devoted to transient and three dimensional electric arcs modelling using direct simulation methodology. Instationary movements of arc due to the self-induced magnetic forces and the influence of fluid flow have been calculated in simple geometry (arcs between plate electrodes). Computations of statistical properties have been performed in order to study the effect of turbulent fluctuations on electric arcs.
