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

RÉSUMÉ

This paper presents performance results and analysis for three compact bubble absorbers developed for generator-absorber heat exchange absorption cycles (GAX). The absorbers employ passive heat transfer enhancement techniques, namely repeated roughness, spiral flutes, and internal spacers. The selection of enhancement techniques was done after a controlling heat transfer resistance analysis of a baseline absorber was completed. Experimental results showed that the enhancement increased the GAX load, increased the vapor flow rate, and decreased the approach temperature difference when compared to the baseline values. However, the performance of each enhanced absorber remained below design goals. Both the vapor injection process and the interior heat transfer coefficient calculation methodology need further improvement to reach design goals.
