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

Arc instabilities play a crucial role in the dynamics of the plasma flow generated by industrial torches such as those used, for example, in plasma spray processes. This study was conducted for a classically designed plasma spray torch, with power supplied by a current regulated rectifier. Arc instabilities were investigated by means of time-resolved measurements of arc voltage fluctuations, which showed very specific features. Numerous experimental results were obtained and correlated with the plasma torch governing parameters, with help of dimensional analysis. At the same time, important temperature and flow velocity variations were observed, which appeared to be strongly coupled to voltage fluctuations.
