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

RESUMO

Finned tube heat exchangers presently used in the air-conditioning industry are made with round tubes (7.0−9.5 mm diameter) and plate fins of an enhanced fin geometry. The air-side pressure drop is composed of friction on the fins and pressure drag on the tubes. This work investigates the use of oval tubes to replace round tubes. This will result in higher heat transfer performance and lower air pressure drop. Of particular interest is application of the oval tube design to refrigerant condensers, which are designed for operating pressures of 31 bar, or more. This paper compares the performance of a proposed oval tube design with that of a typical 9.5 mm finned tube design. Mechanical design and fabrication are also described. A key question addressed in this work is to determine the maximum allowable internal tube pressure of the oval tube design. This question was addressed using 3-dimensional finite element stress analysis.
