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

ABSTRAKT

An experimental study analyzing the complex relationship between external thermo fluid dynamic parameters and the ignition of diesel sprays, as well as flame propagation, is presented. The experiments were performed in a high-pressure, high-temperature system simulating the top dead center conditions in the combustion chamber of a diesel engine. The only simplification with respect to real diesel engines is relative to the aerodynamic pattern. In fact, in this case, the air flux is almost quiescent and does not influence significantly the spray evolution or the combustion behavior.
The influences of two very different injection regimes on the autoignition characteristics of diesel sprays were investigated using imaging techniques. In order to perform this analysis, a careful choice of injection conditions, obtained with two different types of injection apparatus, was necessary. The spray evolution at both low and high temperatures (at the same air density), the temporal and spatial distributions of the ignition points, and the flame growth velocity were measured for the two cases. Analysis of the results revealed the specular behavior of the ignition spatial distributions in the two cases. A first attempt to correlate these different behaviors with the spray-flame interaction is presented, and its implications are discussed.
