Energy Procedia, 2015 AbstractIn this study the equivalent thermal conductivity of foam glass gravels is investigated by means of measurements with guarded hot plate devices. Firstly the thermal conductivity of the foam glass corns is determined. Following experiments are performed on random generated gravel beds varying the mean temperature, the temperature difference ...
