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

Краткое описание

This paper studies the influence of ambient conditions on full flow-field, temporally resolved fuel spray characteristics. The gasoline sprays from a direct-injection (DI) injector are examined for varying ambient air densities, air temperature, and fuel temperatures of practical relevance. The data presented and analyzed in this paper have been obtained utilizing temporally resolved phase Doppler anemometry and high-speed imaging (utilizing Mie-scattering) of the spray. The sprays were characterized in an established high-temperature, high-pressure constant volume rig with large optical access. Results are analyzed and discussed in comparison with the "benchmark" spray characterized at atmospheric conditions. Analysis of the injection event is subdivided into three dominant phases: early, mid, and late phase development, corresponding to the transient injection rate characteristic from a gasoline DI rate tube. In particular, the influence of each ambient parameter on the spray structure and spray quality is analyzed in terms of primary atomization, secondary droplet breakup, coalescence, and droplet vaporization. A test matrix is carefully chosen to enable decoupling of these primary spray phenomena. Elevated fuel temperature is shown to have a significant influence on primary atomization, primarily due to variation of liquid properties. This dataset is extremely useful for computational fluid dynamics model appraisal, while spatial integration of the data enables comparison with previous empirical correlations for first-order approximations of global parametric trends.
