Logarithmic decay of the energy for an hyperbolic-parabolic coupled system

Ines Kamoun Fathallah (2011)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

This paper is devoted to the study of a coupled system which consists of a wave equation and a heat equation coupled through a transmission condition along a steady interface. This system is a linearized model for fluid-structure interaction introduced by Rauch, Zhang and Zuazua for a simple transmission condition and by Zhang and Zuazua for a natural transmission condition. Using an abstract theorem of Burq and a new Carleman estimate proved near the interface, we complete the results...

Modelling of heat and moisture propagation in building structures

Vala, Jiří

Similarity:

The thermal technical analysis is an important part of the design of building constructions. Especially for dwelling structures valid Czech(oslovak) and European standards formulate criteria of maximal thermal stability and minimal energy consumption that have to be verified by credible calculations. The propagation of heat through a building construction, consisting typically of several porous layers, is conditioned by the amount of moisture in such construction; simultaneously it is...
