  1. 1. Steam Drying of Porous Media

    Author : Jörgen Hager; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport coefficients; experimental; heat and mass transfer; sorption isobar; packed bed; porous particles; hybrid model; volume average; porous media; superheated steam; steam drying; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : 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. READ MORE

  4. 4. Light Propagation and Gas Absorption Studies in Turbid Media Using Tunable Diode Llaser Techniques

    Author : Liang Mei; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gas in scattering media absorption spectroscopy; tunable diode laser absorption spectroscopy; frequency modulated light scattering interferometry; light propagation; Absorption spectroscopy; turbid media; diode laser; gas monitoring; porous media; ceramics; food packaging; Fysicumarkivet A:2014:Mei;

    Abstract : 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.

  5. 5. On the Modeling of Porous Media with Emphasis on Localization

    Author : Jonas Larsson; Chalmers University of Technology; []
    Keywords : embedded band; material instability; bifurcation; FEM; softening plasticity; consolidation; shear band; porous media; localization;

    Abstract : 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.
