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

The maximum penetration length of the liquid phase in diesel sprays is of paramount importance in reducing diesel engine emissions. Quasi-steady liquid length values have been successfully correlated in the literature, assuming that mixing of fuel and air is the limiting step in the evaporation process. Since fuel injection in engines takes place at high pressure, nonideal gas effects may significantly affect the phase equilibrium. In this work, real gas effects are implemented into the mixing-limited spray vaporization models of Siebers and of Versaevel et al., taking into account enhancement of the fuel-saturated vapor pressure by the high-pressure ambient gas. Results show that this effect is significant at ambient densities relevant for diesel combustion. The effect of gas pressure on mixture enthalpy (and thereby on liquid length) is also considered but found to be negligible for relevant diesel conditions. Since both models discussed are based on almost the same premises but give different results, their intrinsic differences are evaluated by deriving a new closed-form expression for the Versaevel model. It is shown that the models can be "equalized" by adding a correction factor to the Siebers model, making it physically more consistent. However, for the (limited) data set considered in this paper, this does not improve its predictive capability. It is argued that the remaining error in model predictions is most probably due to the cross-sectional averaging approach.
