Abstract


Based on a dynamic frequency study, the thermal behavior of a wall consisting of a concrete slab contiguous to a panel of compressed rice straw is presented. The thermal behavior at the interface of the two materials is modeled by a thermal contact resistance. The insulating nature wall thus made is studied according the order magnitude of contact resistance: the perfect contact (Rc=0) extreme contact defects (Rc very high). The analysis of temperature and heat flow density curves show that the insulation effects are all the greater as the defects are important.

Author Keywords: concrete slab, straw panel of rice, thermal contact resistance, dynamic frequency regime.


Abstract: (french)


A partir d’une étude en régime dynamique fréquentiel, le comportement thermique d’un mur constitué d’une dalle en béton accolée à un panneau de paille de riz compressé est présenté. Le comportement thermique à l’interface des deux matériaux est modélisé par une résistance thermique de contact. Le caractère isolant du mur ainsi fait est étudié selon l’ordre de grandeur de la résistance de contact : du contact parfait (Rc=0) à des défauts extrêmes de contact (Rc très grand). L’analyse des courbes de température et de densité de flux thermique montrent que les effets d’isolation sont d’autant plus considérables que les défauts sont importants.

Author Keywords: dalle en béton, panneau de paille de riz, résistance thermique de contact, régime dynamique fréquentiel.
