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

Краткое описание

Heat transfer measurement and flow visualization tests were performed to investigate heat transfer enhancement mechanisms of angled ribs mounted on two opposite walls of a rectangular passage with turbulent flow. Seven rib configurations were studied: 90°, 60°, 60°V-shaped, 60° L-shaped, and the broken arrangements for these 60° rib configurations.
It was found that the rotational direction of the secondary flow induced by the ribs plays a dominant role in determining the heat transfer performance. If the rotational direction of the secondary flow is to convey fluid from the central core region of a passage directly to the heat transfer wall, the heat-transfer performance of the wall is augmented appreciably.This is attributed to (1) transportation of colder fluid from the core region to the heat transfer wall and (2) suppression of separated regions behind the ribs through the introduction of higher momentum fluid from the core region of the channel.The mechanism clearly showed the heat transfer superiority of V-shaped ribs over L-shaped ribs.The effects of the rib-induced secondary flow are very strong and remain even if the rotation conditions are employed.
