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

ABSTRACT

An improved header configuration with perforated wing panels was proposed to be installed in pate-fin heat exchangers in order to improve thermal performance. The fluid flow distribution, power consumption, and effectiveness degradation due to the header configuration in conventional and improved headers were calculated and analyzed. The results showed that the fluid flow maldistribution is very serious in conventional headers, where the outlet velocity decreases gradually along the edge of the header, while the perforated wing-panel header configuration can effectively improve the uniformity of the fluid flow distribution, in which the outlet velocity at the center and edge is almost equal. In addition, it was found that when the wing relative height was γ = 0.1, the wing space ratio was β = 0.1, and the wing angle was α = 70°, the comprehensive performance of the improved header is optimum; compared with the conventional header, the flow maldistribution parameter SV of the optimum header decreases by 62.2%–65.1% and the effectiveness degradation rate Δε decreases by 91.9%–93.0%. The corresponding pumping power P penalty increases by 88.1%–90.0%, while the quantity is very little when compared with the overall pressure drop of the heat exchanger. The conclusions in this paper are of great significance in the optimum design header of plate-fin heat exchangers.
