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

SINOPSIS

A novel type of heat exchanger with high potential industrial applications is a flow network consisting of mutually intersecting holes in a plate. A series of empirical studies have been conducted to investigate fluid flow behavior in both a prototype unit and models using various flow visualization methods, such as hydrogen bubble, dye injection, string, particle methods, and laser Doppler velocimetry.
In this article flows in a pair of intersecting ducts with different intersection angles are investigated numerically using commercial software called Fluent. The Renormalization Group (RNG) k-ε model is used to simulate turbulence behavior in the flow.
The numerical visualization technique has successfully revealed turbulent flow characteristics inside the crossing ducts of various intersection angles. The formation of a flow divider and the presence of flow separation regions seen in experiments are confirmed. Three types of pressure-intersection angle relationships are found in different ranges of the intersection angles.
