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

RÉSUMÉ

A Lagrangian−Eulerian based, large-eddy simulation (LES) study of particle-laden turbulent flows is presented. The main focus of the study is a sub-grid two-phase interaction model based on an approximate deconvolution method. This model contributes as a particle source term to the gas phase in the transport equation of sub-grid kinetic energy which, in turn, is used for modeling the sub-grid shear stress. The performance of the model and the overall ability of LES in predicting particle/droplet-laden turbulent flows is discussed based on the test flow configurations of a particle-laden gas jet, particle-laden isotropic decaying flow, and high-speed diesel sprays. The mean and turbulent flow statistics from LES are shown to compare very well with previous experimental and DNS studies. The dependence of the twophase turbulence interaction model on particle loading and Stokes number is found to be consistent with previous DNS analyses. For the isotropic cases, the LES results correctly capture the effect of the particles on different length scales of the flow. The characteristics of different mechanisms contributing to sub-grid kinetic energy are found to be consistent with the previous DNS results. The LES results are shown to be in good agreement with the near-nozzle diesel spray measurement for quantities such as the transverse integrated mass, the mass-averaged axial spray velocity, and the spray momentum. The particle contribution to sub-grid kinetic energy is found to be significant in the conditions of high-particle Stokes numbers, e. g., in the high-speed diesel sprays.
