  1. 11. Modeling Flow and Solute Transport in Packed Beds : Applications in On-site Wastewater Treatment Systems

    Författare :Amir Jourak; Krishna M. Pillai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The use of separate phosphorus (P) filter units containing replaceable filter materials with a high P binding capacity have been suggested as an appropriate passive method to treat the P from pre-treated domestic wastewater in on-site facilities. A large number of materials have been identified and suggested as being potentially suitable for such filters. LÄS MER

  3. 12. Numerical and Experimental Studies on the Effects of Flow on Drop Formation in Cross-flow Membrane Emulsification

    Författare :Anna Timgren; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle image velocimetry; Drops; Force balance model; Membrane emulsification; Volume of fluids; Computational fluid dynamics;

    Sammanfattning : Membrane emulsification is a gentle process that produces emulsions with a narrow drop size distribution, which increases the stability of the emulsion. The dispersed phase is forced through the pores in a membrane and drops are formed at the other side of the membrane where a continuous phase, flowing along the membrane surface, sweeps away the forming drops.

  4. 13. Foam modeling including pore gas interaction for crashworthiness analysis

    Författare :Mats L Landervik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Hyperelasto-viscoplasticity; Non-linear dynamics.; Staggered solution; Theory of Porous Media; Constitutive modeling;

    Sammanfattning : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. LÄS MER

  5. 14. Fluid flow through and deformation of wood fiber networks

    Författare :Patrik Pettersson; Veronique Michaud; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Cellulose-based commercial items such as paper and laminated flooring are vital to the local economy of northern Sweden. These products are commonly manufactured in suspension where fluids such as water or air are drained through the fiber network in some value-added steps in the manufacturing process. LÄS MER

  7. 15. Turbulent and Transitional Flow in Porous Media An Experimental Investigation

    Författare :Shervin Khayamyan; Wook Ryol Hwang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Fluid flow through porous media takes place in many natural processes such as ground water flows, capillary flows in plants and flow in human organs and muscles. It is also of outmost importance to have knowledge of this flow in a number of industrial processes such as paper making, making of fiber boards, composites manufacturing, filtering, forming and sintering of iron ore pellets and drying and impregnation of wood.
