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

RÉSUMÉ

The present study deals with the local heat transfer of ribbed surfaces. The whole ribbed surface is divided into six subregions according to different flow patterns over the subregions. They include separated and redevelopment regions on the base surface between ribs with a large rib pitch and cavity region on the base surface with small rib pitch, front, top and back regions on the rib surface. The local heat transfer coefficient in those subregions have been experimentally investigated over a wide range of Re ( = 3 × 103 − 1 × 105), hp/De ( = 0.0324 − 0.174), p/hp ( = 2.5 − 60) and qp/qb ( = 0.5 − 2.5). The relationship between the local Nusselt number and these parameters are discussed and empirical correlations for the local Nusselt number are proposed. Experiments are performed with a rectangular test duct having a smooth upper and ribbed lower wall. Air of atmospheric pressure and room temperature was used as the working fluid.
