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

Enhancement of forced convection is important in many engineering applications. Surface modifications like rib-roughening are commonly used in applications such as compact heat exchangers and cooling systems in gas-turbine systems. In this paper flow fields, friction factors, and local and average heat transfer coefficients in rib-roughened ducts of the type appearing are considered. Both experimental and numerical investigations are discussed. Details of the flow pattern and the influence of rib configuration, rib angle, rib pitch, and rib height are discussed and physical interpretation of the results are provided. Some general conclusions are provided but it is also found that accurate numerical modelling of the flow and heat transfer from ribbed surfaces is difficult. Suggestions for further research are given.
