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

摘要

An improved Channel Arc Model for simulation of AC arcs on ordinary PC's is presented. In this model the arc is treated as a cylindrical current conductor with uniform radius and a prescribed radial temperature distribution. In order to verify the model, laboratory arcs with I mrs ≈ 1000 A, as well as industrial arcs with I mrs ≈ 100 kA, are simulated and compared to measured values. Assuming symmetrical furnace conditions, the three-phase electric circuit is first simplified to a one-phase description which is compared to values from an industrial submerged arc furnace. In order to generalize the model, and to be able to simulate also asymmetrical furnace conditions, the complete three-phase circuit is included and results obtained from the three-phase simulations are compared with one-phase simulations. In addition, the effect of a charge current, which bypasses the arc, is shown in the three-phase description.
