Abstract

Thermal properties evaluation with a transient method in powder melts and model describing different physico-chemical phenomena comparison R Baffler, H. Sailed, P. Labeau* * Laboratoire de Thermodynamique et Physico-chimie Metallurgiques France ^ Centre Scientifique et Technique du Batiment France Abstract For high temperature reactors or construction materials, thermal barriers are usually fabricated with porous materials. Their thermal properties depend on complex physical or physico-chemical phenomena (solid conduction, gas conduction, thermal contact resistances, gas convection in pores, surface reaction, surface radiation...). They have to be taken into account in the different theoretical models. The normalised measurement methods for thermal properties need long time stabilisation and brick materials. The evaluation with small amount of materials using simple setup is now possible with transient methods. They are helpful to generate a database for the use in thermal modellin
