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

Краткое описание

Aiming at improving the air-side thermal-hydraulic performance of the assembled compact fin-andtube radiator, an innovative wasp waist tube is proposed which is deformed from the traditional flat tube. The thermal-hydraulic performance of the wasp waist tube with different aspect ratios was compared with the flat tube using numerical analysis. The results showed that the heat transfer capacity of the wasp waist tube was better than that of the flat tube. The wasp waist tube with an aspect ratio of L/W = 5 was then selected with consideration of heat transfer capacity and manufacturing factors. Furthermore, the geometrical parameters of the louvered fin associated with the wasp waist tube were also optimized using the orthogonal experiment method. Various simulations were carried out using different models of varying air velocities and optimal parameters, namely, Fp = 2.52 mm, Lp = 1.5 mm, Lw = 3.58 mm, La = 23°, were found among the cases studied. Finally, wind tunnel experiments were also carried out to compare the wasp waist tube radiator with the circular, oval, and flat tube radiators. The results showed that the proposed wasp waist tube and louvered fin structure could improve the air-side heat transfer of the compact radiator, which can be applied not only in the automobile industry but also in other potential applications.
