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

The objective of the present experimental work is the study of local heat transfer performance over a target plate under impingement of inline and staggered jet arrays by a liquid crystal thermograph technique. Three jet-to-target spacings Z (= z/d) of 3, 6, and 9 with inline and staggered jet arrays were considered at jet Reynolds numbers Re = 1500, 3000, and 4500 in three different exit-flow orientations. The results show that the local heat transfer rates are characterized by obvious periodic-type variation of Nusselt number distributions. The downstream peaks are diminished with increasing cross-flow effect. The best heat transfer performance is obtained with the cross flow exiting from both ends of the impingement channel. The inline jet array produces relatively higher local and overall heat transfer rates than those of the staggered jet array. Additionally, in the present results of 3 ≤ Z ≤ 9, higher heat transfer rates are found for the system with a smaller jet-to-plate spacing.
