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

The paper presents results of an experimental investigation carried out to study the effect of relative roughness pitch and perforation of the spring roughness (by changing coil pitch of the helical spring) on heat transfer and friction factor for turbulent flow in an asymmetrically heated annular duct (radius ratio = 0.39) with a heated tube having a spirally wound helical spring. The spring diameter to hydraulic diameter ratio is 0.11. The relative roughness pitch ranges from 4.09 to 8.18, while the relative coil pitch is 2.66−4.5. The maximum enhancement in the Nusselt number over the smooth annulus ranges from 95 to 172% for Spring 2 (with a relative coil pitch, pc/d, of 2.66 arranged at a relative roughness pitch, p/e, of 4) while the lowest enhancement of 54−81% is seen for Spring 12 (pc/d = 4.5; p/e = 8) in the flow Reynolds number range of about 4000−14,000; the Nusselt number ratio, Nu/Nus, has been found first to increase with an increase in the Reynolds number up to about 10,000 and then decrease. The corresponding enhancement in the friction factor values is 193−307% and 116−137%, respectively. Thermal performance comparison at equal pumping power for the roughened and smooth annuli shows performance advantage of 32−83% for Spring 2. Nusselt number and friction factor correlations have been developed for the most preferred type of roughness.
