  2. 21. Thermal Characterization and Modelling in Microsystem Packaging Applications

    Author : Elisabeth Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon nanotubes; Thermal management; Transient Hot Wire; Composite; Microchannels; Anisotropic Conductive Adhesive;

    Abstract : As the electronics circuits grow denser and the power consumption per area unit is increasing, new more efficient technologies for heat removal is necessary. Heat fluxes from the integrated circuit, IC, in the order of 100W/cm2 are not rare. READ MORE

  4. 22. Thermal Modelling of the Caledonian Basin, Scandinavia and a Northern North Sea Profile

    Author : Jörgen Samuelsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; petroleum; vitrinite reflectance; thermal maturation; flexural rigidity; heat flow; suppression; thermal conductivity; North West Shelf; Alum Shale;

    Abstract : The reason for the registered high paleotemperatures of the Scandinavian Alum Shale was investigated by heat flow modelling constrained by vitrinite-like reflectance. The behaviour of the lithosphere under a load was modelled and the paleotemperatures were explained by burial of the Alum Shale in a foreland basin, developing during the Caledonian orogeny.

  5. 23. Heat and water transfer for lacquer drying and thermal signatures : modelling, simulation and experiment

    Author : Ricardo Garcia-Padron; Roland Wimmerstedt; Linköpings universitet; []
    Keywords : ;

    Abstract : The coupled phenomenon of heat and water transfer is essential in many scientific and industrial problems. This thesis focuses this phenomenon on two areas; lacquer drying and thermal signatures. Simulations of physical phenomena may in some cases replace extensive experimental investigations, which may be complicated and expensive. READ MORE

  6. 24. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

    Author : Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Abstract : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

  7. 25. Dynamic Solid Oxide Fuel Cell Modelling for Non-steady State Simulation of System Applications

    Author : Miriam Kemm; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; termodynamik; applied thermodynamics; Termisk teknik; Transient analysis; Technological sciences; Teknik; Energy research; Energiforskning; Thermal engineering; Thermal stress; Solid Oxide Fuel Cell; Fuel cell modelling;

    Abstract : Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. READ MORE
