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

To study the heat and mass transfer phenomena of atomic oxygen at the solid/gas interface of thermal protection system, we propose to model a low pressure plasma reactor and to qualify by a simulation the recombination and the energy transfer by accommodation of oxygen atoms to a target surface at stagnation point configuration. The flow is described by a system of conservation (momentum, mass and energy) equations and Maxwell-Gauss equation solved by using a Computational Fluid Dynamics code (CFD-ACE®). Model parameters are issued from experimental parameters (reactor volume and geometry, flow rate and composition...). The simulation of plasma phase was performed to compare two kinetic models giving the evolution of the main species (e-, ions, radicals, atoms...) occurring in the plasma. Two surface reactions have been added to these gas phase models. We have obtained the field velocity, temperature and the fluxes of atomic and molecular species (oxygen and nitrogen) in the reactor under similar conditions to experiments. The originality of this work is the capability to characterize the electric field of the plasma discharge along the reactor.
