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: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RÉSUMÉ

An efficient parabolized numerical procedure is developed for calculating a highly confined, chemically reacting turbulent flow. The conservation equations of mass, momentum, energy, and species concentration, together with the strong coupling of heat and mass transfers at the solid burning surface are numerically solved using a finite volume method. The standard k−ε turbulence model is used, and turbulence closure is achieved using a two-layer model that takes into account the wall-injection effect arising from the burning surface. Interaction between turbulence and combustion is modeled by Eddy-Dissipation Concept with fast chemistry. A two-dimensional adaptation of the Discrete Ordinates Method is used for estimating the flame radiation energy to the burning wall. The influence of various parameters (crossflow mass flux, radiation, oxygen concentration and confinement) on the regression rate, the flow velocity and the temperature was investigated. The predicted regression rate is in relatively good agreement with the available experimental data, and is a function of the crossflow mass flux raised to the nth power with n=0.681 for the confined flow.
