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

SINOPSIS

A novel design algorithm is developed for application of enhanced heat transfer technology in evaporative fluid coolers (EFCs). In spite of substantial increase in heat transfer rate, application of these devices can lead to a non-negligible pressure drop, so it is necessary to consider pressure drops in design algorithm directly. In this paper, first the plain tube bundle for EFCs is examined by a new design algorithm and then the thermal appraisal of enhanced bundles is mainly targeted. In this study, application of a typical tube insert in EFCs was investigated. It is determined that by considering the maximum allowable pressure drops, maximum heat and mass transfer coefficients and the minimum required area can be obtained in a straightforward manner. The algorithm is easily adaptable when the other various types of heat transfer enhancement devices are applied inside or even outside of the tube bundle of EFCs. The results are revealed that, depending on the enhancement device, while the heat transfer area required for a given duty is reduced the heat transfer and mass transfer coefficients can be increased significantly.
