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: 1.2 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: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

摘要

Brachial burning and gasification-split characteristics of two droplets situated in a forced convection are analyzed by means of numerical method. For the given droplet size ratios of 1.5 and 0.25, it is found that a tri-brachial burning in the former and a penta-brachial burning in the latter are exhibited, where the brachial burning and gasification split are defined according to the envelope flame formation and destruction. When the droplet size ratio is large, the two droplets are always enclosed together in a flame for low Reynolds numbers. As Reynolds numbers are higher, the flame is destroyed and brought to deposition behind the two droplets. Two or three gasification-split points are induced in accordance with the Reynolds number undergoing, thereby producing the tri-brachial burning. On the other hand, for a lower droplet size ratio such as 0.25, under certain conditions the flame surrounds only the trailing droplet, yielding a semienvelope flame. As a result, two extra brachial burn ing based on the variation of the semienvelope flame are defined, and the penta-brachial burning is obtained. Accordingly, the multiple burning states around two interactive droplets, including pure vaporization, wake flame, transition flame, envelope flame, and semienvelope flame, are established, except for the low Reynolds numbers in which only envelope flame develops. The new findings presented in the present article provide comprehensive insight for the development of droplet model in spray combustion, by intrinsically considering the variations of the Reynolds number around droplets.
