    Sammanfattning : The thermoelectric effect was discovered nearly 200 years ago, but it started to be utilized for waste heat recovery fairly recently. From the economical point of view, such application requires a cheap and efficient material, which is able to convert heat energy into electricity. LÄS MER

  4. 9. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations

    Författare :Raheb Mirzanamadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal properties; slippery condition; hydronic heating pavement; energy harvesting; asphalt concrete; road; anti-icing; finite element method;

    Sammanfattning : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. LÄS MER
