TWO-PHASE THERMAL CONDUCTIVITY OF CERAMIC SPONGES WITH AND WITHOUT FLOW UP TO HIGH TEMPERATURES
Résumé
This publication reports about the two-phase thermal conductivity (also often called effective thermal conductivity) of ceramic sponges (= open-celled foams). Experimental results for the two-phase thermal conductivity with and without flow for different sponge types are presented. The temperature was varied up to 1000 °C, where thermal radiation has to be considered as one important heat transfer mechanism. The results were correlated using the well-known Rosseland equation, a thermal resistance model and a Péclet approach for describing thermal radiation, heat conduction and forced convection effects.
