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

摘要

It is very significant for the effective design and operation of bubbly equipments to understand deeply the liquid turbulence modulation mechanism by bubbles. In the present paper, detailed investigations on modulation of bubbles on the liquid turbulence, for the dilute bubbly flow with a low liquid-phase Reynolds number, were carried out with the developed Euler-Lagrange numerical method when bubbles always stayed in different turbulence layers for the horizontal and vertical channels, respectively. The velocity field of the liquid phase was solved with direct numerical simulation (DNS), and the bubble motion was followed with Newtonian motion equations. The present studies show that the liquid-phase turbulence modulation is tightly related to the bubble location and the momentum transfer direction between bubbles and liquid (i. e., the gravity direction); it should be noted that when bubbles are located in the turbulence buffer layer, the opposite phenomena happen to the liquid turbulence modulation by bubbles for the horizontal and vertical channels.
