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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

RÉSUMÉ

Heat transfer characteristics in a triangular duct cooled by an array of side-entry tangential jets has been studied experimentally. A right-angle triangular duct with an apex angle of 45° is tested under different jet Reynolds numbers and jet spacing. Coolant is provided by an array of equally spaced wall jets aimed at the leading-edge apex and exits from the radial outlet. Detailed heat transfer coefficients are measured for the two walls forming the apex, using a transient liquid-crystal technique. Secondary flow structures are visualized to realize the mechanism of heat transfer enhancement by swirl jets. Results show that an increase in the jet Reynolds number increases the heat transfer on both walls. Moreover, local heat transfer on both walls gradually decreases downstream due to the crossflow effect. Finally, area-averaged heat transfer coefficients on both walls have been correlated with the jet Reynolds number.
