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

ABSTRACT

In this paper, experimental work has been performed to analyze the heat transfer and flow characteristics in spirally fluted tube annuli with large variations of the fluid properties. The objective of this paper is to develop a Nusselt number correlation considering the property variation effect on the heat transfer performance. This paper investigates the effects of property variations not only in radial direction but also in axial direction on the heat transfer rate. The effect of property variation on the heat transfer rate increased as the Prandtl number increased. The property variation effect on heat transfer rate was more significant in laminar flow than in turbulent flow. A new correlation of the Nusselt number that considered the property variation effect with ±20% error bands was developed for annulus flow with a fluted inner tube. The correlation can be applied for the cases in which the fluid property changes significantly: i.e., Pr range of 2−32, the temperature difference between the wall and the bulk fluid up to 40°C, and the axial temperature variation up to 73°C.
