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

Convection heat transfer in open-cell foams mainly occurs under thermally developed conditions for both uniform temperature and heat flux boundary conditions at the solid/fluid interface, since few cells are in the entrance region. Therefore, convection heat transfer needs to be thoroughly studied in order to allow reliable predictions of foam performance. A numerical analysis of fully developed laminar convection in open-cell foams at a pore scale is presented in this paper. The geometry of the cell is chosen making reference to Kelvin's tetrakaidecahedron foam model. The finite-element-based commercial code COMSOL Multiphysics (COMSOL Inc., Burlington, MA, USA) is employed in building up the numerical grid and solving the problem for different porosities and Reynolds numbers. The local velocity and local interfacial convective heat transfer coefficient in a cell in the thermal fully developed region are predicted. The results highlight the dependence of velocity on foam porosity and the effect of porosity on flow separation. They also exhibit a periodical behavior of the local convection heat transfer through the cell affected by the porosity and Reynolds number. Finally, cell-averaged heat transfer coefficients and average Nusselt numbers are presented, which highlight the effects due to scale changes.
