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: 0.5 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: 0.8 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: 0.2 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

要約

Full knowledge of gas-liquid flow in a swirl vane separator is essential for separator design and performance improvement. In this paper, three-dimensional numerical investigations on swirling flow and separation performance are carried out. The detailed flow field, pressure loss, and grade efficiency are obtained numerically. Results show that a long and narrow wake is induced downstream of the swirl vanes and the static pressure in this region is lower than that near the external wall. The pressure loss in the swirl vane part occupies a large proportion of the total pressure loss. The gas velocities, including axial and tangential components, decrease a relatively small amount downstream of the swirl vanes and the strong swirling flow can persist for a long distance until the top outlet. The radial velocity is at least one order less than the other two velocities and has little influence on the droplet separation. The distribution of the droplet size has a great influence on separation performance and there exists a critical value for both grade efficiency and pressure loss. The critical droplet size depends strongly on the separator design and operation conditions.
