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

RÉSUMÉ

The speckle-photographic method that has become an attractive alternative to traditional optical flow visualization methods is described and modeled by means of the Fourier analysis. The speckle displacement due to the presence of a flow with varying fluid density is verified with numerical simulation in the case studied. The speckle displacement as the signal is a measure of the refractive light deflection, similar to the information obtainable with a schlieren system; but the analysis visualizes the principal differences between the physical effects used for schlieren and speckle measurements. In order to avoid the shortcomings of this "line-of-sight" method in resolving three-dimensional test objects, an attempt is made to combine the speckle technique with the "sharp-focusing" effect known from schlieren technology. Preliminary experiments with a flow of known density distribution demonstrate that the implementation of "sharp-focusing" can deliver spatially resolved results.
