    Abstract : A chute spillway is a typical component of large dams for discharging floods. Because of the high water head, the flow velocity in the chute is often in excess of 20 m/s. Consequently, the structure is usually prone to cavitation damages. Flow aeration is evidenced to efficiently eliminate or to mitigate the damages. READ MORE

  5. 3. Simulations of the Dynamics of Fibre Suspension Flows

    Author : Stefan B Lindström; Tetsu Uesaka; Myat Htun; Fritz Bark; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre; fibre suspension; simulation; paper; papermaking; forming; fibre orientation distribution; fibre flexibility; viscosity; first normal stress difference; fluid flow; simple shear flow; two-way coupling; three-dimensional; Chemical engineering; Kemiteknik; Engineering physics; Teknisk fysik;

    Abstract : A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.

  6. 4. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

    Author : Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

    Abstract : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. READ MORE

  7. 5. Numerical modeling of groundwater and air flow between compacted bentonite and fractured crystalline rock

    Author : Benoît Dessirier; Jerker Jarsjö; Andrew Frampton; Stefan Finsterle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two-phase flow; porous media; fractured media; compacted bentonite; crystalline rock; numerical modeling; geological disposal; Physical Geography; naturgeografi;

    Abstract : The geological repository for final storage of spent nuclear fuel, envisioned by the Swedish Nuclear Fuel and Management Company (SKB), relies on several barriers: copper canisters deposited in holes in the floor of underground tunnels in deep bedrock, embedded in a buffer of compacted bentonite. The initially unsaturated buffer would take up water from the surrounding rock mass and swell to seal any potential gap. READ MORE
