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

ABSTRAKT

A parallel computational code for the execution of the Proper Orthogonal Decomposition (POD) of turbulent flow fields is developed. The POD is an analytically founded statistical technique that allows the extraction of appropriately defined modes of the flow from the background field, allowing the determination of the coherent structures of turbulence. The technique operates through the selection of a basis for a modal decomposition of a set of signals, to be processed with the use of the spectral theory of compact self-adjoint operators. Details are given on computational aspects with regard to the different phases of the numerical method and the development of the related parallel code is described. Computational tests corresponding to different domains and number of processors are executed on a HP 9000-V2500 parallel computer and the results are shown in terms of parallel performance of the different phases of the calculations separately considered, and of the computational code as a whole.
