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

Краткое описание

The vortex-induced gas entrainment at free surface should be avoided in the reactor vessel of the liquid metal fast breeder reactor. Since the gas entrainment was induced by the small vortex dimple at free surface, the characteristics of the vortex dimple should be evaluated. In this study, the velocity distributions around the vortex dimple at free surface were measured by a new particle image velocimetry technique. The test section was the vertical cylindrical tank having a free surface. The vortex dimple was formed at the center of the cylindrical tank. The local three-dimensional velocity distributions around the vortex dimple were measured by the velocity vector histogram (WH) method, which was proposed by the authors. In the conventional WH method, a three-dimensional velocity vector histogram was constructed, which needed lots of computer memories. To improve the accuracy and to reduce the memories, a new algorithm were applied to the conventional WH method. In the construction of the histogram, the three-dimensional histogram was divided into three one-dimensional histograms, i.e., the projection histograms. With applying the new algorithm, the more accurate velocity distributions were calculated.
