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

要約

The natural convective thermal field in the air around a horizontal isothermal cylinder with a longitudinal plate fin is visualized by means of laser holographic interferometry. The cylinder is either heated or cooled to maintain a constant surface temperature, while either a copper (conducting) or a balsa (insulating) fin is attached longitudinally on the cylinder at various circumferential locations to grasp the effect of fin-air interaction on convective flow patterns that appear in the form of interference fringes. As a result, a vertically ascending (in the heated cylinder case) or descending (cooled case) plume interacts with an air stream along the fin. Subsequently, it is discovered that an optimal circumferential fin location exists at which local heat transfer performance around the cylinder becomes uniform. The optimal circumferential location is unaffected by fin material and is unchanged, always situated downstream of the plume irrespective of the cylinder being heated or cooled. An additional experiment is performed on frost formation on a cooled cylinder. It is found that a substantially more uniform thickness of frost is formed on the cylinder surface when a fin is attached on the optimal circumferential location than in the absence of a fin.
