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 penetration of fuel spray under diesel engine conditions was calculated by solving the cross-sectionally averaged equations for unsteady two-phase flow. The effects of a variety of processes in the spray, e.g., air entrainment and droplet evaporation, on spray penetration are analyzed through the corresponding nondimensional parameters. The integrated two-phase flow equation system can further be simplified with the approximation of equal gas and liquid velocities, which are reached after a short atomization region for a complete spray. A closed-form solution for the penetration length was derived from the system of integrated equations using the quasi-steady-state assumption. This solution is compared with the well-known Wakuri correlation and the Hiroyasu correlation. The expression of the spray tip and droplet penetration lengths are also deduced for nonconstant injection velocity. The effects of ambient air density and droplet evaporation rate on spray penetration were investigated numerically, and the numerical results agree very well with many experiments from the literature.
