  2. 21. Thermal Plasmonic Metasurfaces

    Author : Gustav Edman Jönsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Plasmonic materials can form viable optical absorbers that offer new possibilities for device designs as they potentially have large optical cross-sections with readily tuned spectral positions and widths. Applications for such materials include heat generation via optical absorption. READ MORE

  4. 22. 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

  5. 23. Experimental and numerical investigations of underhood flow for vehicle thermal management

    Author : Randi Franzke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; MRF; Laser-Doppler anemometry; Underhood flow; Axial fan; Cooling flow; RBM; Vehicle thermal management; Simplified underhood environment;

    Abstract : Electrified vehicles are an essential part in reducing emissions from the transportation sector. Their development comes with a variety of new challenges. Most of them revolve around the energy efficiency of the vehicles as it directly relates to the range that can be covered with one charge. READ MORE

  6. 24. Thermal conductivity of wide and ultra-wide bandgap semiconductors

    Author : Dat Tran; Plamen Paskov; Vanya Darakchieva; Martin Kuball; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-nitrides; β-Ga2O3; Thermal conductivity; Thermal transport;

    Abstract : This PhD thesis presents experimental and theoretical studies of the thermal conductivity of wide and ultra-wide bandgap semiconductors including GaN, AlN, β-Ga2O3 binary compounds, and AlxGa1−xN, ScxAl1−xN, YxAl1−xN ternary alloys. Thermal conductivity measurements are conducted using the transient thermoreflectance (TTR) technique and the results are interpreted using analytical models based on the solution of the Boltzmann transport equation (BTE) within the relaxation time approximation (RTA).

  7. 25. Thermal Study of a Submerged Substation for Wave Power

    Author : Antoine Baudoin; Cecilia Boström; Didier Saury; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; marine substation; heat transfer; natural convection; CFD; FEM; thermal management;

    Abstract : At the Division of Electricity of Uppsala University, a wave power concept is being developed.It relies on wave energy converters, one buoy and one linear generator placed on the seabed, connected together to a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE
