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

SINOPSIS

The aim of the present study is to estimate the influence of convective heat exchanges on the cooling process of a rotating solid or heat pipe disc, subjected to an air flow parallel to its surface. The application to the TGV brake-disc-cooling during the braking phase is carried out. For a rotating disc in superposed air flow, the latter is a dominant factor in the heat transfer coefficient. The modelling of the heat transfer is achieved in solid and heat pipe discs, when simultaneously subjected to convective losses and entering heat flow. The simulation is validated through tests carried out on different model discs. Finally, the particular application to the rail braking (TGV) is completed. The temperatures computed inside the heat pipe brake-disc rotating in still air, during the braking phase remain lower than those obtained inside the solid brake-disc in superposed air flow.
