  2. 1. Internal erosion in embankment dams : fluid flow through and deformation of porous media

    Author : J. Gunnar I. Hellström; Thanasis D. Papathanasiou; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. READ MORE

  4. 2. Fluid flow through and deformation of wood fiber networks

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

    Abstract : 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. READ MORE

  5. 3. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems

    Author : Henrik Ström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea-SCR; particle trapping; flow-through filter; urea decomposition; diesel particulate matter; particle motion; particle filter; AdBlue-spray; Eulerian-Lagrangian modeling;

    Abstract : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. READ MORE

  6. 4. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters

    Author : Shahin Akbarnejad; Ragnhild Elizabeth Aune; Pӓr Jönsson; Andreas Westermoen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. READ MORE

  7. 5. Converter Interfaced Distributed Generation - Grid Interconnection Issues

    Author : Fainan Magueed; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSC; harmonics; LCL-filter; power quality; weak grid; voltage regulation; vector control; strong grid; distributed generation; intentional islanding; L-filter; voltage dips;

    Abstract : Distributed generation (DG) with a converter interface to the grid is found in many of the green power resources applications. In this thesis, the control of a voltage source converter (VSC), as the DG front end, is in focus regarding the power quality problems that could appear at the connection point. READ MORE
