In this paper experimental results of pressure drop and heat transfer for different ceramic sponges (variables: material, ppi number and porosity) are presented. The pressure drop data is correlated using an Ergun-type equation, which yields to an accuracy of 20%. The heat transfer coefficients were determined by a transient method and correlated in dimensionless form (Nusselt number) by a power law of Reynolds and Prandtl number. Furthermore the applicability of the well known Generalized Le´veˆque Equation (GLE) on solid ceramic sponges is checked. The GLE provides a correlation between pressure drop and heat transfer. The investigation shows that the tendency observed for the data corresponds with that of the theoretical model.
