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 local convective boiling measurements in a micro-fin tube** for four pure refrigerants: R22, R32, R125, and R134a; and four refrigerant mixtures: R410B (R32/125, 45/55% mass), R32/R134a (27/73% and 30/70% mass), and R407C (R32/125/134a, 25/23/52% mass). All testing was conducted using a counterflow water-heated horizontal 9.5 mm (Do) U-tube with helical micro-fins. Saturation temperatures ranged from 274.5 K to 293.6 K. Flow boiling heat transfer coefficients for the mixtures' pure components and R22 were measured to establish a baseline for the heat transfer degradation calculations. The measured convective boiling Nusselt numbers for all of the test refrigerants were correlated to a single expression consisting of a product of dimensionless properties valid for mass velocities ranging from 70 kg/m2·s to 370 kg/m2·s and for vapor qualities between 0 and 0.7. These measurements were within ±20% of the new correlation predictions for 94.6% and 87.3% of the pure refrigerant and mixed refrigerant measurements, respectively. The correlation was shown to predict some existing data from the literature to within 20%. The degradation in heat transfer performance of the mixtures was found to range from 1% to 50% for all refrigerants tested.
