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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

RESUMO

An experimental study is performed to investigate effects of an active control technique proposed herein, named peripheral shear flow, on blowout limits and lift-off tendency of turbulent jet diffusion flames. This technique is achieved by ejecting air peripherally from a rectangular tube set at a position off the center of a fuel nozzle where a jet flame is formed. Here the main stream of air does not hit the flame directly but its periphery intervenes with the flame surface to form shear flows. It is found that (1) flame blowout limits and lift-off heights are extended and lowered, (2) the base of a lifted flame is anchored to positions desired by varying axial displacements of the tube, and (3) the above effects are attributed to mixing enhancement as well as the formation of large-scale vortices when this technique is applied.
