Sammanfattning : The present study concerns heat and mass transfer in porous media dried by superheated steam. Specifically, the steam drying process of a packed bed of porous particles was studied in order to obtain design data for a band drier. LÄS MER
Sammanfattning : Porous materials are present in many natural as well as engineered structures. Engineering examples of porous materials include sandstone in which oil can be stored, earth dams, composite materials, air filters and sanitary products with fiber networks (e.g. diapers). LÄS MER

4. Light Propagation and Gas Absorption Studies in Turbid Media Using Tunable Diode Llaser Techniques
Sammanfattning : Optical absorption spectroscopy is a widely used analytical tool for constituent analysis in many applications. According to the Beer-Lambert law, the transmitted light intensity through a homogeneous medium is an exponential function of the product of the concentration, the total pathlength, and the absorption cross-section of the absorbing substance.

Sammanfattning : The mechanics of porous media is nowadays relevant in a broad spectrum of engineering applications. In the case of geomaterials, the description of the mechanical behavior is complicated by the fact that the deformation characteristics involve (strain) localization, which is indeed the main topic of this thesis.
