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

ABSTRAKT

This paper presents performance results and analysis for three compact bubble absorbers developed for generator-absorber heat exchange absorption cycles (GAX). The results were found as part of a study undertaken to develop a compact GAX absorber for incorporation into the distillation column of an absorption machine. It has been shown that enhancement techniques are effective in reducing absorber length. However, enhancement techniques must be carefully applied, enabling sufficient vapor volume fractions for needed vapor injection. Results show that solution circuitry or flow configuration significantly impact absorber performance. Results also show that increased solution tube diameters may increase absorber performance: namely, an increase in absorber load and a reduction in exit solution subcooling. Optimum compact bubble absorber designs require a careful balance between vapor introduction capacity and heat transfer augmentation.
