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

Flash boiling spray can produce superior atomization and promote the fuel/air mixture formation for gasoline direct injection engines, which are further capable of reducing fuel consumption and harmful emissions. Most recent studies on flash boiling spray focus on the macroscopic characteristics. The microscopic characteristics (i.e., diameter and velocity of droplets) of flash boiling spray, which determine the combustion and exhaust emissions in internal combustion engines, are not well explored yet. In flash boiling spray, the high number density of droplets causes serious multiple scattering, low signal to noise ratio, and high deviation of droplet diameter, making most of the well-known techniques for measurements of microscopic characteristics of droplets unsuitable for flash boiling spray. Thus, the extended glare point velocimetry and sizing technique is improved and utilized for the measurement in this paper. The droplet size and velocity of flash boiling spray were obtained under various conditions of fuel temperature and ambient pressure for the first time. It was found that flash boiling has the effects of promoting the atomization process, reducing the local Sauter mean diameter (SMD), and narrowing the diameter distribution of the droplets. Additionally, the overall results demonstrate that flash boiling spray is an effective approach for producing fine droplets with uniform size.
