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

RESUMO

Local thermodynamic equilibrium (LTE), frequently used as first approximation in modeling of thermal plasma processes, is sometimes unable to explain experimental results. It is particularly true near a wall and a surface impacted by the plasma jet. In this work, a 2-D custom model using the CFD commercial code Fluent was developed for argon-oxygen inductively coupled plasma (ICP) at atmospheric pressure. The assumption of thermal equilibrium was made but not that of chemical equilibrium. The transport properties were calculated using higher-order approximation of Chapman-Enskog theory. Reaction kinetics rates of dissociation and ionization were also considered. The model was applied to a process torch used for carving experiments on graphite, and the distribution of reactive species brought to the surface was analyzed in terms of reaction rate distribution: the experimental effect of different injection geometries on the distribution of the reaction rate is qualitatively reproduced by the model.
