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

This study aimed at a better understanding of the transient nature of axisymmetric gas jets and sprays under diesel conditions. To evaluate the performances of the Reynolds-averaged Navier-Stokes (RANS) and the large eddy simulation (LES) modeling approaches, a comparative computational study using both methodologies has been performed for the same computational cases with the same numerical algorithm and spatial resolution. The results show that LES is capable of capturing the unsteady features of transient gas jets and sprays such as flow vortical structures, whereas RANS is incapable of resolving these features. Furthermore, the excessive dissipation in the RANS simulation can lead to underprediction of the jet penetration, while LES can better represent the jet mixing and entrainment, which offers a promising tool for numerical prediction of transient jets and sprays.
