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

要約

To address the problem of studying the effects of the torch design on a supersonic argon-hydrogen plasma flow, a mathematical model is developed and validated with published experimental work. The model predicts the aerodynamics, thermal and electric fields inside the torch and includes a non-equilibrium cathode sheath model. The theoretical results reveal that supersonic and subsonic plasma torches have different behaviors. It is concluded that the design of supersonic torches should not be based on subsonic torch designs. The model is also used as a tool to evaluate the operating parameters, namely the electric power and chamber critical pressure, that should be used for various torch designs in order to obtain a shock free supersonic plasma jet.
