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

要約

A 500-μm-wide and 11-mm-deep cross-microchannel, which is made of copper and attached by a hydrophobic nanoporous membrane having a pore size of 0.22 μm and a porosity of 70%, is tested in the present study to examine the characteristics of gas/liquid two-phase flow in the microchannel in horizontal and vertical orientations during bubble venting via the hydrophobic nanoporous membrane. The mass flux tested in the present study is 5, 7.5, 10, and 12.5 kg/m2·s. In addition, the quality in the present study is tested from 0 to 0.08. The effects of mass flux, quality, and microchannel orientation on both the gas/liquid two-phase flow pattern and the bubble venting efficiency are examined in the present experiment through direct flow visualization. The tested results show that the farthest bubble movement distance increases with quality. It is also found that the flow rate of residual gas with the vertical arrangement is larger than that of the horizontal orientation. This is because the buoyancy force is in favor of the horizontal configuration for providing more direct contact and such contact of the bubble and the membrane is helpful for bubble venting. Besides, it is found that the higher flow rate of residual gas leads to a higher-pressure drop gradient in the flow channel.
