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

摘要

The objective of this study is to investigate the effect of incident shock waves on flameholding behind a fuel injection strut in low temperature supersonic flow, and to elucidate the structure of the flameholding region. A non-premixed hydrogen flame was established behind a fuel injection strut in Mach 2.5 supersonic airflows with total temperature between 400 K and 900 K. The shock waves interacted with the wake behind the fuel injection strut, which improved the flameholding characteristics remarkably by enlarging the recirculation flow and enhancement of mixing. The incident position and the strength of the shock waves control the size of the recirculation flow and flameholding limit. As the strength increases, the upper limit of fuel flow rate for flameholding increases. As the incident points of the shock waves move downstream from the strut base, the upper limit decreases and finally the flame is not stabilized for any fuel flow rate. Instantaneous OH distribution in the flameholding region was observed by laser induced fluorescence. The main reaction occurs near the base at the small fuel flow rate. As the flow rate increases, OH distribution moves downstream and varies between the front and the middle section of the wake. On the other hand, homogeneous OH distribution is observed around the rear throat region of the wake until the blow-off. This suggests that the upper flameholding limit is largely determined by the stability of flame base in the throat region.
