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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RÉSUMÉ

A study of fuel spray characteristics for different fuels from multi-hole nozzle injectors was performed. Two different injection systems were used on two test rigs. A main feature of the hot ambient temperature system (hot bomb) used was that analysis of all the fuel plumes could occur at one time, and all the plumes were imaged on the same piece of film. Spray behavior was examined for five different fuels and for ambient temperatures up to 500 K in the hot bomb. The results yielded tip penetration length and spray cone angle for each of the spray plumes from a six hole injector. A second system was used to perform the droplet size measurement under room temperature condition (cold bomb), and the two most different fuels were selected for the experiments.
The results in this paper show how the spray plumes behave as they leave each of the six holes of the injector. The characteristics of each hole differ during injection. The variations of spray cone angle and tip penetration length between holes are small but significant. These variations in tip penetration and cone angle changed as the temperature of the chamber changed, but the overall characteristics of the spray plumes changed only slightly for the temperatures used in this paper. The effect of fuel viscosity on the spray tip penetration length is insignificant. Higher viscosity fuels gave smaller spray cone angles and larger overall average droplet sizes.
