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

ABSTRAKT

A transient numerical simulation on the response of counter-flow gaseous diffusion flames was carried out over the entire range of stretch rates with the fuel and oxygen ambient temperatures as varying parameters. The model assumes an overall chemical reaction but with flame radiation loss. The shapes of steady flame response curve obtained include "isola" at low ambient temperatures and "ghost" at high ambient temperatures. A cyclic flame ignition and quenching phenomenon was discovered in a low stretch region with moderate ambient temperatures. This paper presents the computed response curves and, in particular, the time-resolved cyclic event. In addition, a map using ambient temperature and stretch rate as coordinates is given to show the various regions of the diffusion flame response.
