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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

To simulate the dynamic characteristics of the oscillating bubble plume in a rectangular bubble column, three-dimensional transient simulations are performed using the FLUENT commercial software based on the volume of fluid (VOF) approach. In order to take into account the influence of the movement of the free surface of the liquid phase on the oscillations of the bubble plume, the numerical simulation domain corresponds to the geometrical dimensions of the column. The reproduction of the dynamic flow behavior with the VOF model dominated by the oscillating movement of the bubble plume is encouraging. The time-averaged liquid velocity field obtained from the VOF simulation shows that the liquid is entrained upflow in the core region and downflow near the walls. The simulated vertical velocity profiles are in agreement with particle image velocimetry (PIV) measurements near the column walls and at its center. The gas holdup is greater at mid height of the column; however, near the interface the gas holdup was notably reduced.
