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

The limited accuracy and parametric range of two-phase heat transfer correlations for internally-grooved tubes have impeded the widespread application of this most promising technology. The success of regime-based analyses and correlations in providing improved predictive accuracy for heat transfer coefficients in smooth tubes has motivated this effort to explore the relationship between two-phase flow regimes and heat transfer rates in internally-grooved tubes. Following a brief introduction to the geometries and manufacturing techniques of internally-grooved tubes and a description of the state-of-the-art smooth tube flow regime maps, fundamental studies of thermofluid performance in internally-grooved tubes are reviewed and analyzed to demonstrate the relationship between flow regime and evaporative heat transfer rates. Then, the current state of two-phase flow regime maps and heat transfer coefficient correlations for internally-grooved tubes are summarized. Finally, recommendations for future internally-grooved tube research directions are given. The majority of the studies herein deal with halogenated fluids in conventional-sized tubes at standard temperature and pressure. However, studies of small diameter tubes, as well as alternative refrigerants and reduced pressure, are also considered.
