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: 2.3 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: 1.8 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: 0.2 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

摘要

Heat transfer and fluid flow characteristics in a round tube fitted with circular ring flow blockages were studied. The experiments were conducted on a heat exchanging tube fitted with circular rings, with a circumferential gap between the ring and inner wall of the tube as well as rings in the wall-attached position. Circular rings were selected as flow blockage geometry and configured with a different inner diameter to achieve flow blockage areas of 30%, 40%, and 50%. Moreover, each ring blockage had a different outer diameter to achieve a gap of 0 mm (no gap; i.e., wall-attached position), 1 mm, 2 mm, and 3 mm between the ring and tube wall. Parameters varied during the tests were flow blockage area (FBA), gap, and Reynolds number. The pitch diameter ratio was kept constant for all inserts. Air with ambient temperature was used as a working fluid in a test tube in which the inner wall is maintained at uniform heat flux. The Reynolds number varied from 6000 to 24,000. A significant effect of the gap between the outer circumference of the ring and the inner wall of the tube was observed on pressure drop as well as the rate of heat transfer across the test section. Among the tested inserts, insert (50.1) with a circular ring of 50% FBA and 1 mm gap gives the highest enhancement in the rate of heat transfer, which is 3.51 times compared to the smooth tube at higher Reynolds number. Insert (30.0)−that is, the circular ring that offers flow blockage area (30%) and in a wall-attached position−gives the highest overall performance factor (1.26) at a lower Reynolds number.
