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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

SINOPSIS

Numerical simulations of the exact (DNS) or filtered (LES) Navier-Stokes equations are of great importance for analysis of physical phenomena and development of models for any turbulent flow. However, these tools need accurate initial fields and adapted treatments for the boundary conditions. This paper suggests some numerical procedures to generate any turbulent field with prescribed parameters. These fields may be used as initial or boundary conditions for any DNS or LES computation but also as a way to visualize a synthetic turbulent field reconstructed from experimental statistics. First of all, the Rogallo method for the generation of a turbulent velocity-vector field is given in detail. Then, a new procedure to generate any scalar field with prescribed statistics and characteristic length scales is proposed. Eventually, a procedure to initialize the initial dispersion of a Lagrangian spray field is presented. Again, the characteristic sizes of the clusters of droplets and their local density are entirely controlled.
