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: 1.7 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: 1.4 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

ABSTRACT

In this paper, the hydraulic performance of single-phase water inside a novel microfinned flat tube is experimentally investigated with the Reynolds number less than 4000. The effects of fin geometrical parameters and section aspect ratio on the pressure drop of the microfinned flat tube are studied, and results show that the pressure drop would significantly increase compared to the smooth tubes due to the fluid in the flat tube has higher flow velocity for the same Reynolds number. However, compared with the flat tube, the microfinned flat tube performs with slightly higher pressure drop, which can be explained by the increase of the wall roughness. Based on aforementioned characteristics, a new correlation of single-phase friction factor for the fl at tubes has been developed. At the same time, the correlation that described the friction factor of the microfinned flat tube is proposed according to the empirical correction of the flat tube with a reasonable correction. The uncertainty and error of the correlation are analyzed, which can predict the experimental data with the deviation less than 10%.
