CHARACTERIZATION OF THERMOPHYSICAL PROPERTIES OF SILICA GEL
SINOPSIS
In this work, an experimental characterization study of a granular porous media, i.e., Rubin silica gel, which is already well known for its hygroscopic properties, is presented. A comparison of both dry and wet conditions is performed. For this purpose, we will rather focus on the determination of the thermophysical properties of this media because there is a lack of studies in this field in the literature. The characterization has been experimentally done by using the method called "box". The thermal conductivity and the thermal diffusivity were measured and analyzed. The specific heat capacity was determined by the measured thermal conductivity, the measured thermal diffusivity, and reported silica gel density for both states. The obtained results lead to a better comprehensive control of the media response regarding the heat flux imposed and will be used later in a simulation investigation of heat and mass transfer in a reactor filled with silica gel.
