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

This paper reports the experimental results of the basic performance of a GCH4/GO2 small thruster with a swirl-coaxial injector. The effects of the equivalence ratio of CH4/O2 mixtures and the swirl intensity of the O2 injector on the combustion characteristics of the combustion chamber were studied. It was found that applying swirl to the O2 jet greatly improved the thruster performance by increasing the mixing rate between the propellants. The performance was also influenced by the equivalence ratio. Direct observation in the combustion chamber showed that when the swirl intensity of the O2 jet was small, the flame lifted at low equivalence ratios and the rim stabilized flame was formed at high equivalence ratios. For higher swirl intensity, only a lifted flame was developed over the range of the equivalence ratio tested. The tendency is explained by the ratio of the angular momentum of the O2 jet to the linear momentum of CH4 jet. The lifted flames had a favorable effect on the mixing between the propellants, resulting in the good thruster performance. Emission spectra from the flame in the combustion chamber were measured to make the combustion process clear. The measurement showed that the various reactions including the generation of OH, CH and C2 initially proceeded on the injector side. The formation order and intensity variation of the species were discussed.
