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

ABSTRACT

We performed thermal visualization to determine unsteady heat transfer in a flow through an array of slanted fins installed vertically on a heated surface coated with a thin sheet of thermosensitive liquid crystal. The fins are arranged in in-line and staggered forms. The fin angle, transverse pitch, and longitudinal pitch are varied. The convective heat transfer phenomena can be visualized as color distribution on the liquid crystal sheet which exhibits temperature variation. Color image processing is performed on the visualized images to determine the quantitative temperature distribution through a hue angle-temperature correlation curve, and thus we can represent the unsteady temperature distribution for convective heat transfer. We also performed flow visualization of flow patterns through the fin array. The Nusselt number for convective heat transfer between the heated surface and the cold fluid is calculated from the temperature distribution. Pressure drop for the flow through the fin array is measured and is expressed in the form of the coefficient of pressure loss. Results are correlated as Nusselt number versus coefficient of pressure loss for fin angles, fin arrangements, and flow patterns.
