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

ABSTRACT

The present spray combustion computation studies numerically the effects of spray angles and injected droplet sites on the combustion efficiency and combustion modes of a cylindrical, nonpremixed combustor through implementation of a realistic droplet combustion model. Combustion efficiency increases with increasing spray cone angle, achieving a maximum value at an optimal injected mean droplet size. The predicted combustion modes indicate that fuel is consumed by the complementary processes of droplet and gas-phase combustion, and are significantly influenced by both spray cone angle and injected mean droplet size. Two flame patterns are identified based on injected droplet size. Small droplet spray is characterized by a diffusion flame separating the fuel and air streams, while large droplet spray exhibits intense mixed droplet and gas-phase combustion near the combustor watt. The results show that combustion efficiency for the former and latter increases and decreases, respectively, with increasing injected droplet sizes. The optimal injected droplet size is therefore suggested to occur at the transition between these two flame patterns.
