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: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRACT

This study is to investigate the characteristics of heat transfer of a horizontal tube, equipped with radial fins of triangular profile, immersed in a high-temperature fluidized bed. The heat transfer variations are compared with those of a smooth tube experimentally.
The finned tubes and smooth tube, with outside and inside diameters of 48.6 mm and 30.6 mm, are made of steel. The depth of the fin is 5 mm and the angles of fin are 25°, 30°, 35°, 40°, 45°, and 50°. Experiments are conducted at three different bed temperatures of 720, 800 and 880°C. A granular refractory (silica sand) is used as bed material with mean particle diameters of 0.96 mm and 1.37 mm.
The maximum heat transfer coefficient is achieved by the rake angle of 25° for the particle size 0.96 mm of bed material, and by the rake angle of 30° for the particle size 1.37 min. These coefficients are about 2 and 1.8 times higher than the case for the smooth tube, respectively. The heat transfer coefficient for the finned tube is greater than that for the smooth tube. Also the rake angle of the finned tube for the maximum heat transfer coefficient changes depending on the particle size of bed material, and the effect of the rake angle becomes more distinct as the bed temperature increases.
