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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRAKT

Most industrial applications consuming a much primary energy, such fuel and gas, used different technologies of burners. The thermal efficiency and polluting emissions depends on the burner nozzle, on the fuel type and oxidant type (air or pure oxygen). This article is interested by the dynamic study in a coaxial burner consisting by two coaxial circular jets: a central jet to inject natural gas and the annular jet for pure oxygen injection. The aim of this work is the experimental study of two free coaxial jets with flame disposed in ambient air and to have the effect of varying equivalence ratio on the flow structure. This study carried in three configurations; two configurations made in lean combustion mode (Φ = 0.65, Φ = 0.8) and the stoichiometric configuration (Φ = 1). The variation in the amount of oxygen in the combustion reaction affects on the longitudinal velocity, on the transversal velocity and on the turbulent fluctuation. These parameters are very important and affect directly on the flame structure. The reduction of equivalence ratio leads to increased of longitudinal and transverse velocity and promotes the fluctuation in interaction zone between natural gas and oxygen. At the stoichiometric reaction, the turbulent intensity represents a maximum in the mixing zone. This maximum increases when the height above the burner increases.
