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

It is widely known that mixing in reacting sprays is an important factor in the determination of the flame lift-off length, which is the location where the flame stabilizes. These details can be captured with computational techniques using computational fluid dynamics with a very fine mesh resolution. Use of a coarse resolution overpredicts mixing due to large numerical diffusion and thus reduces the predicted lift-off length. Even though a recently developed gas jet spray model improves the prediction of the spray structure with coarse mesh resolution, predictions of vapor mixing in evaporating sprays are still mesh-dependent. In this study, a subgrid-scale model based on classical jet theory is presented, where the vapor-air mixing is modeled with a combined Lagrangian and Eulerian approach. The vapor is transported as a Lagrangian particle consistent with jet mixing and transport theory until the jet mixing is resolved by the mesh scale. In this way, the results show improved predictions of vapor tip penetration and flame lift-off length using coarse-mesh resolutions. The new model offers a potential tool for investigating reacting sprays using coarser mesh resolution to save computational time for complete cycle simulations of internal combustion diesel engines.
