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

This paper presents a study on the heat transfer coefficient of flow in a rectangular duct with a swirler using thermochromic liquid crystals. The experiments were conducted in the purpose- built perspex rectangular duct with an aspect ratio of 1:5. One side of the duct was heated by an electrical heater which generated a uniform constant heat flux over the surface. The variation of the Reynolds number was 13,000−24,000. Thermochromic liquid crystals were sprayed on the top of the duct surface forming a temperature sensitive layer. Swirlers with vane angles of 30°, 45°, and 60° to the flow axis were used in the experiment. From the results obtained, it was found that the thermal performance of the air flow through the rectangular duct with a 60°−swirler is the best among those used in this study.
