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

The influence of fuel pressure on diesel spray evolution into a quiescent environment at two temperatures (300 and 800 K) has been analyzed by means of a laser light scattering technique. Two-dimensional measurements have been made of scattering intensity and its polarization state on cross sections of the spray. The theoretical and experimental aspects of the technique and the interpretation of the measured quantities are presented. The results indicate that a wide variation of the conditions of fuel injection into a room-temperature environment (fuel peak pressure from 500 to 1400 bar) does not change the liquid surface area significantly between 7 and 14 mm from the nozzle. However, the same variation of fuel pressure influences the spray evolution very much in the same spatial region for injections into a high-temperature environment. In this case a high injection pressure (peak pressure of 1400 bar) results in an increase of the liquid surface area along the spray, whereas a relatively low pressure (peak pressure of 500 bar) results in a decrease. Some reasonable explanations of this behavior are discussed, considering the possible effects due to atomization, evaporation, coalescence, turbulent dispersion, and inertial evolution of the spray.
