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: 0.5 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: 0.8 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

RÉSUMÉ

Boiling flow and heat transfer in porous media composed of spherical fuel elements have a significant influence on a reactor's efficiency and safety. In the present study, an experimental setup is designed and the boiling flow and heat transfer in porous media composed of regularly distributed spheres are investigated. The test sections mainly consisted of a polycarbonate plate for observation, an aluminum plate with densely distributed hemispheres, and a layer of glass spheres. The water flowing in the porous channels was heated by electrical power through the aluminum plate with hemispheres. Four types of spheres with diameters of 5, 6, 7, and 8 mm were involved. In the experimental parameter range, four flow regimes (bubbly, bubbly slug, slug, and slug annular) were observed to consider the effects of heat flux, mass flux, and particle diameter. The boiling heat transfer results showed that larger particles lead to a lower heat transfer coefficient and result in a higher wall superheat of the original nucleation boiling. Finally, a correlation between the boiling heat transfer coefficient and the measured data is proposed.
