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: 1.7 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: 1.4 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: 0.6 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

Краткое описание

This study examined the flow boiling heat transfer characteristics in horizontal rectangular microchannels with hydraulic diameter of 0.5 and 1.0 mm. Experiments were performed with R30 refrigerant under the following conditions: heat flux 1-16 kW·m-2, mass flux 111-333 kg·s-1·m-2, and vapor quality 0-0.35. The results showed that heat transfer was strongly affected by heat flux and vapor quality, while the mass flux remained less influential. The effect of flow regime transition on heat transfer coefficient was discussed through parameter analysis. Previous correlations have been examined and none of them can predict new data with satisfactory accuracy.
