Anil Kumar, Auteur ; M. Prakash Maiya, Auteur ; S. Srinivasa Murthy, Auteur Année de publication : 2012 Article en page(s) : pp. 12990–12999 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Thermal conductivity Résumé : The effective thermal conductivity (ke) of a MmNi4.5Al0.5 hydride powder bed was measured using an one-dimensional steady-state axial heat transfer comparative method. The experiments showed that ke lies between 0.1 and 1.2 W/m K in the pressure and the temperature ranges of 0–50 bar and 0–100 °C, respectively. While hydrogen pressure and concentration showed strong influence on ke over the complete range, the temperature effects were minimal. Thermal conductivity of the solid materials, MmNi4.5Al0.5 alloy and its hydrides, was also back calculated from the experimentally measured ke values.
