Convective Heat Transfer In Porous Ceramic Materials


Abstract: In this study heat transfer in porous ceramic materials, which offer a potential as an alternative heat transfer medium in a number of systems in which heat transfer takes place, is investigated experimentally. Experiments were performed for five different specimens at various air flow rates and specimen temperatures. The volumetric heat transfer coefficient was determined using the results of the experiments. A characteristic length obtained from the pressure drop data was used in order to define Reynolds number and Nusselt number. A correlation equation between Nusselt number and Reynolds number was obtained for each specimen tested.
