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

A three-dimensional model for the simulation of inductively coupled plasma torches (ICPTs) working at atmospheric pressure has been developed, using customized CFD commercial code FLUENT© . The helicoidal coil is taken into account in its actual 3-D shape, showing its effects on the plasma discharge for various geometric, electric and operating conditions. The electromagnetic equations are solved in their vector potential form, while the steady flow and energy equations are solved for optically thin plasmas under the assumptions of LTE and laminar flow; some of the results that will be presented have been obtained by means of an improved turbulent version of the 3-D model. Simulations are performed over a network cluster of double processor calculators in order to use the full capabilities of the 3-D modelling to describe the gas injection section of an industrial TEKNA PL-35 plasma torch without geometry simplifications, in order to perform a more realistic simulation of the inlet region of the discharge. In order to evaluate the importance of various 3-D effects on calculated plasma temperature and flow fields, our new results have been tested against the ones obtainable from 2-D models and from improved 2-D model that includes 3-D coil effects. Three-dimensional results concerning different operating conditions are presented, together with simulations of the trajectory and heating history of powders injected in the torch through a carrier gas.
