  2. 16. Steam Drying of Porous Media

    Author : Jörgen Hager; Avdelningen 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. 17. Membrane emulsification: modelling interfacial and geometric effects on droplet size

    Author : Marilyn Rayner; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore geometry; membrane emulsification; Gases; Surface Evolver; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; modelling; Livsmedelsteknik;

    Abstract : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. READ MORE

  5. 18. Detection and 3-D positioning of small defects using digital radiography, 3-D point reconstruction, and tracking

    Author : Erik Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pore Defects; Radiographic Testing; Nondestructive Evaluation; Laser Welded Titanium; Multiple Hypothesis Tracking; X-ray Testing;

    Abstract : The weight and quality concerned aero industry is constantly trying to decrease the excess material in their components. With decreased weight the fuel consumption can be lowered and the negative environmental effects from aviation decreased. READ MORE

  6. 19. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

    Author : Anders Kullingsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

    Abstract : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. READ MORE

  7. 20. Extension of PC-SAFT to model inhomogeneous and transport properties

    Author : Gulou Shen; Georgios Kontogeorgis; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : CO2 separation plays an important role in greenhouse gas emission mitigation, in bio-fuel production via biomass gasification as well as in biogas upgrading. The current CO2 separation technologies are energy intensive, and new cost-effective CO2 separation technologies are needed. READ MORE
