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

RESUMO

The modified drop drag (MDD) model was further improved and implemented in the KIVA code for better describing the liquid fuel spray characteristics in diesel engine combustion chambers. The MDD model accounts for the effects of both the drop's frontal area and its drag coefficient as a function of its distortion on drop drag and drop breakup. The new version of the KIVA code with the MDD model was tested for the cases of the free liquid spray and the spray/wall impingement on a solid wall from single-hole fuel injection nozzles in high pressure chambers at room temperature condition. The results from numerical calculation by using the new version of KIVA code with the MDD model and the experimental data were in good agreement for both the free liquid spray and the spray/wall impingement cases. In addition, in the spray/wall impingement case the effect of the MDD model was seen to be very important on both the spray penetration and the wall spray height after impingement. In contrast to earlier models, it was found that the calculated data were insensitive to the choice of the breakup time constant, B1, after impingement. This indicates that the physics of drop destabilization processes following wall impingement are accounted for more reasonably with the MDD model.
