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

RESUMO

Mixing and combustion processes within a supersonic flow in a rectangular duct with a centrally mounted plate injector have been investigated. A supersonic air stream is generated inside this duct using the highspeed flow developed by a vitiated air heater. Hydrogen fuel is injected parallel into this flow, with the resultant mixing and combustion investigated using different optical and laser based diagnostic techniques.
Mixing studies have been performed in a non-reacting supersonic flow to investigate both the compressibility effect of a supersonic mixing layer and a shock induced mixing layer enhancement technique. The results show a pronounced decrease of the normalized growth rate of the compressible mixing layer, whereas shock impingement onto the mixing layer results in a slight growth rate enhancement. Planar laser-induced fluorescence of OH has been applied in order to characterize the combustion process within the supersonic flow field.
