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

RESUMO

This study investigated a new enhanced boiling surface made by wrapping wire mesh on low-fin tubes. Pool boiling performance of the new enhanced tubes was tested with refrigerant 134a at 5,10, and 26.67°C saturation temperature for 6−48 kW/m2 heat flux. Brass or copper mesh of 80,100, or 120 mesh per inch was wrapped around finned tubes of 42, 50, or 60 FPI (fins per inch). The fin heights were either 0.2 mm or 0.4 mm. The test results show that mesh-covered fin tubes yielded significantly enhanced boiling performance. The influence of fin geometry is more pronounced with mesh than without mesh. The preferred mesh size decreases with decreasing heat flux. The surface made by wrapping brass mesh of 100 mesh per inch on 60 FPI tube having 0.4 mm fin height yielded the best boiling performance. It enhanced the boiling heat transfer coefficient by 3−8 fold at 5−26.7°C as compared with the smooth tube.
