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

RÉSUMÉ

The atomization of electrically insulating liquid fuels has been investigated using the charge injection method with consideration of its usefulness as a spray combustion technique. This requires electrostatic spraying systems that atomize unadulterated commercial grades of fuel oil sufficiently finely while being able to operate robustly in the ionized combustion environment. As a natural consequence of the liquid charging mechanism, the atomization quality improves with flow rate because of the dual action of aerodynamic shear and the higher specific charge that can be achieved in the liquid jet. At moderate charging conditions, sprays of insulating liquids are similar to those of semiconducting liquids, with a core of larger drops surrounded by a sheath of much smaller companions. More highly charged sprays are more homogeneous, and stable combustion of kerosene and diesel oil has been achieved for the first time at practically useful flow rates. Flame stability improves with atomization quality and a stable flame seat is formed without the need for a pilot flame for an atomizer of 150-mm orifice diameter for a kerosene flow rate of 0.5 ml/s and a specific charge of 3.0 C/m3. Spray manipulation of both cold and combusting sprays using DC electric fields has been demonstrated, and the effectiveness of the technique suggests that optimization of the combustion process is possible by applying AC electric fields.
