Modeling of thermally driven resonance at multiscales / P. Srinivasan in Journal of heat transfer, Vol. 133 N° 11 (Novembre 2011) 

Public ISBD [article]  in Journal of heat transfer > Vol. 133 N° 11 (Novembre 2011) . - pp. [112402/1-10] Titre : Modeling of thermally driven resonance at multiscales Type de document : texte imprimé Auteurs : P. Srinivasan, Auteur ; S. Mark Spearing, Auteur Année de publication : 2012 Article en page(s) : pp. [112402/1-10] Note générale : Physique Langues : Anglais (eng) Mots-clés : Thermal  wave  Resonance  Phonons  Multiscales Index. décimale : 536 Chaleur. Thermodynamique Résumé : Understanding the mechanisms of thermally driven resonance is a key for designing many engineering and physical systems especially at small scales. This paper focuses on the modeling aspects of such phenomena using the classical Fourier diffusion theory. Critical analysis revealed that the thermally induced resonant excitation is characterized by the generation of multiple wave trains with a constant phase shift as opposed to the single standing wave generated in a mechanically driven resonant response. The hypothesis proposed herein, underpin a broad range of scientific and technological developments and the analytical treatment enables design of thermally driven resonant systems with improved performance.
