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: 2.3 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: 1.8 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

摘要

This paper describes an experimental study of single-phase air flow and heat transfer inside a spirally corrugated tube with an inlet axial vane swirler. Three spirally corrugated tubes and six inlet axial vane swirlers are used with different geometry parameters and spiral directions. Results show that the combined use of spirally corrugated tube and inlet axial vane swirler can enhance the convective heat transfer inside a tube, but with the disadvantage of friction factor increase. The compound angle formed by the spirally corrugated tube and the inlet axial vane swirler has a marked influence on the compound enhancement effect. For same conditions, the combination of the spirally corrugated tube with the inlet axial vane swirler in the opposite spiral direction has a higher heat transfer coefficient, a higher friction factor and a higher thermodynamical performance than that in the same spiral direction. The compound thermodynamical performance curves are also presented. It is showed that with the same pump power and same heat transfer area, the heat flux transferred by the spirally corrugated tube with an inlet axial vane swirler can be increased up to 1.9 times, compared to the smooth-tube values. Finally, a new method is proposed for correlating the compound friction and heat transfer experimental data.
