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

An experimental study is performed to determine the mechanism of flow through louver-finned surfaces by means of flow visualization and laser Doppler velocimetry (LDV). The louver angle and flow velocities are varied. Results are obtained for the velocity vector, turbulence intensity, Reynolds stress, and power spectrum together with images of flow patterns in both the fin and louver spaces. It is disclosed that an increase in the louver angle promotes enhancement in mixing performance but the appearance of a separation bubble in the vicinity of louver-fin connection bend limits the louver angle. Large longitudinal vortices are induced in flow through all louvered fins. The uniqueness of the louver-finned system is its arched geometry which serves as a curvature producing the centrifugal force for the enhance mixing performance. Applications of such a system are abundant in compact heat exchange devices most well known in automotive radiators.
