Public ISBD [article]  in Journal of heat transfer > Vol. 134 N° 5 (Mai 2012) . - 07 p. Titre : DSMC scheme for phonon transport in solid thin films Type de document : texte imprimé Auteurs : Mitsuhiro Matsumoto, Auteur ; Masaya Okano, Auteur ; Yusuke Masao, Auteur Année de publication : 2012 Article en page(s) : 07 p. Note générale : heat transfer Langues : Anglais (eng) Mots-clés : phonon  dynamics;  thermal  analysis;  direct  simulation  Monte  Carlo  (DSMC)  scheme; Index. décimale : 536 Chaleur. Thermodynamique Résumé : Analysis of phonon dynamics based on a linearized Boltzmann transport equation is widely used for thermal analysis of solid thin films, but couplings among various phonon modes appear in some situations. We propose a direct simulation Monte Carlo (DSMC) scheme to simulate the phonon gas starting without the conventional linearization approximation. This requires no relaxation time as an input parameter, and we can investigate the couplings among phonons with different modes. A prototype code based on a simple phonon model was developed, and energy flux was evaluated for thin films of various thickness as a test calculation.
