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

A droplet suspension of liquid fuel produced by an ultrasonic atomizer was ignited using an electric spark. The Sauter mean diameter (SMD) of the droplet suspension was 57μm to 66 μm for fuel injection rates of 2.13 cm3/min to 4.44 cm3/min, respectively. The droplet distribution for any fuel injection rate included a negligible amount of droplets smaller than 20 μm or larger than 100 μm in diameter. The flame ball propagating outward was monitored by observing light emission from OH- and C2-radical bands using photomultipliers, a highly sensitive CCD camera, and a high-speed camera. Thereby, the mechanism of flame propagation and the complicated structure of spray flames were observed. It was found that a nonluminous flame was propagating continuously through a gas-phase mixture, followed by luminous flamelets, such that a number of small-scale droplet clusters with luminous emissions appeared randomly and discontinuously behind the flame front propagating in a premixed combustion mode. This result shows that the group structure of spray flames is not simple.
