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

This paper focuses on the use of direct numerical simulation (DNS) in the context of spray atomization modeling. Key features of such liquid/gas simulations, which are necessary for confidence in model accuracy, are recalled and discussed together with their inherent limitations. Particular attention is given to the lack of theories relating to the determination of the smallest length scale in turbulent liquid-gas flows. To demonstrate how direct numerical simulation can serve modeling purposes, this paper discusses three major areas of possible applications of DNS. First, DNS databases were created to validate modeling approaches inflow areas where no experimental measurements are available. In this paper, this approach is applied to diesel injection conditions to validate the Eulerian−Lagrangian spray atomization (ELSA) model. Second, because models are necessary to mitigate computational costs, which constitute the main drawback of DNS, this paper proposes the development of a large eddy simulation formulation of the liquid atomization, thereby enabling results that are no longer mesh resolution dependent. Finally, once the large scale is correctly captured, it is necessary to ensure an accurate representation of the liquid structure falling below the subgrid scale. To this end, a source term for the surface density equation is established based on direct numerical simulations of liquid-gas flows embedded in an isotropic turbulence and covering both dense and moderately dense ranges.
