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

ABSTRAKT

Experiments were carried out on turbulent jet diffusion flames, with the focus placed on the lift-off flame morphology in the interim of doublet flow utilization to investigate the alteration pattern of the flame. Real-time imaging video recording, as well as image processing and treatment devices, were employed. Doublet flows are formed with the concentric annulus, in which fuel jet is injected up from an inner fuel nozzle while air from the surroundings is sucked into the outer tube encompassing the nozzle. It has been found that (1) real-time imaging recording and timewise variation of flame image analysis were able to grasp a real picture for flame lift-off phenomena, (2) statistical and quantitative treatment for flame liftoff heights and base widths was the correct approach for the morphology analysis, and (3) flames oscillated immensely above the fuel nozzle with frequent reattachment when volume flow rate of air was set to the maximum, which validates the positive effect of doublet flows on enhancement of flame blowout limits.
