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

Heat transfer results are presented for a rotating disk cooled with an impinging air jet directed on its free surface. In this study local heat transfer distribution was investigated for a disk freely rotating in space. Then, the effect of rotation and jet impingement were examined. Several important factors, such as rotational Reynolds numbers, jet Reynolds numbers, jet-to-disk spacing and finally location of the jet center relative to the disk center were considered. The disk rotational speed was varied from 250 to 4000 rpm while three jet Reynolds number of 6800, 24000, and 48000 were used. Jet-to-disk spacings of 2 to 8 jet diameters were selected while the jet-to-disk diameter ratio was kept constant at 0.09. The jet was placed perpendicularly to the disk surface at four different distances from the center of the disk. These distances were, zero cm (center-to-center), 3.5 cm, 6.9 cm and 8.9 cm. The heat transfer from the disk was measured using a transient technique which employed liquid crystals. A nearly uniform wall temperature thermal boundary condition was achieved for the disk by constructing an enclosed insulated oven with well-controlled heating elements.
