Abstract: Metal and ceramic solid foams were examined to determine axial dispersion for liquids (water and 45% glycerol solution) single phase flow; the results obtained for the packed bed of spheres were used for comparison. The influence of the liquid...

Abstract: Morphological parameters of the solid foams have been determined using computed microtomography, optical microscopy and helium pycnometry. For the first technique, impacts were studied of the voxel size and method of the image binarization...

Abstract: Metallic foams appear as promising catalyst carriers for fast catalytic reactions. They combine many beneficial properties, like large specific surface area, high porosity and relatively low pressure drop. The foams can be regarded as an intermediate...

Abstract: In this paper, the morphological parameters and transport coefficients are studied for the reticulated vit-reous carbon (RVC) foams of pore density 30 and 80 PPI. SkySkan 1172 X-ray microtomograph was used to study the foam structure. Heat...

Abstract: The liquid holdup was determined experimentally for a trickle bed reactor with the solid foam filling. It was found that the commonly applied drainage time is too short to determine the liquid holdup properly. The liquid holdup was correlated...

Abstract: Flow resistance and transport properties for air flow through metallic NiCr foam were experimentally studied. The foam was considered as a catalyst carrier in structured reactors. Heat transfer coefficients were determined by foam heating by...
