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

SINOPSIS

The structure of lean premixed methane-air flames at atmospheric pressure conditions has been studied using a planar laser-induced fluorescence (PLIF) technique. The burner geometry used in this investigation, which simulated a single burner in a typical gas turbine combustor, consists of a central nozzle surrounded by two concentric annuli. Three independently varied parameters—the radial swirl distribution in the outer annulus, the axial momentum in the inner annulus, and the premixed equivalence ratio—were used to investigate the flame structure. The spatially resolved PLIF technique allowed obtaining instantaneous and ensemble-averaged OH images at vertical cross sections of the flame (referenced through the centerline) under different flame conditions. These images provide qualitative information on the flame reaction zone, which is of interest for understanding the complex structure and dynamics of a swirling premixed combustion system. These images also assist in understanding why lean premixed gas turbine combustion systems may experience combustion instability, particularly under leaner conditions.
