  1. 21. Physical process effects on catchment-scale pollutant transport-attenuation, coastal loading and abatement efficiency

    Författare :Georg Lindgren; Georgia Destouni; Roko Andricevic; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Efficient pollutant load abatement; groundwater-surface water interactions; biogeochemical cycles; nitrogen; Lagrangian stochastic travel time approach; GIS; Hydrology; Hydrologi;

    Sammanfattning : Pollutants follow various subsurface and surface water pathways from sources within a catchment to its outlet and may cause detrimental effects on downstream water quality and ecosystems. Along their different transport pathways through a catchment, pollutants may be attenuated subject to different physical and biogeochemical processes. LÄS MER

  3. 22. Prediction of Cooling Air Flow in Electric Generators

    Författare :Pirooz Moradnia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

    Sammanfattning : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. LÄS MER

  4. 23. Feedback thermotherapy for benign prostatic enlargement : A clinical and methodological evaluation

    Författare :Lennart Wagrell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; benign prostatic hyperplasia; transurethral microwave thermotherapy; feed-back thermotherapy; intraprostatic blood-flow; intraprostatic temperature; bladderneck; PET; Kirurgi; Surgery; Kirurgi; kirurgi; särskilt urologi; Urology;

    Sammanfattning : The purpose of this thesis was to evaluate a new treatment strategy for symptomatic benign prostatic enlargement.The transurethral thermotherapy (TUMT) antenna design was studied. The design influences the heating-profile significantly and the absorbed energy in a target volume were only about 13-20% of the energy delivered. LÄS MER

  5. 24. Valve-less diffuser micropumps

    Författare :Anders Olsson; KTH; []
    Nyckelord :;

    Sammanfattning : Today there is growing interest in research on microfluidicsystems, e.g., for chemical analysis systems and microdosagesystems. One of the basic components in microfluidic systems ismicropumps. LÄS MER

  7. 25. Void formation and transport in manufacturing of polymer composites

    Författare :Staffan Lundström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : In this thesis void formation and removal during the Resin Transfer Moulding process are considered. The problem is examined by doing real moulding as well as mouldings under microscope, model experiment and analytical computations. The materials utilised are in most cases glass fibre reinforcements and vinylester resins. LÄS MER
