Résumé

Certaines applications en transfert radiatif nécessitent la prise en compte d'un déséquilibre fréquentiel sans pour autant requérir la grande précision d'une méthode cinétique. Le modèle aux moments présenté a pour objectif d'étendre les possibilités du modèle M1 proposé par B. Dubroca et J.L. Feugeas [2] pour pouvoir résoudre de telles applications, tout en restant hyperbolique et physiquement consistant. Pour citer cet article : R. Turpault, C. R. Acad. Sci. Paris, Ser. I 334 (2002) 331-336.

Abstract

Though not requiring the great accuracy of a kinetic method, several applications of radiative transfer need to take into account quantities which are not constant over all the frequencies. We introduce a moments model which aims at extending the possibilities of the M1 model proposed by B. Dubroca and J.L. Feugeas [2] in order to solve such applications and keeps the hyperbolicity and physical consistency. To cite this article: R. Turpault, C. R. Acad. Sci. Paris, Ser. I 334 (2002) 331-336.
