    Abstract : Global climate is adversely affected by increasing emissions of carbon dioxide and other green-house gases. The road transport sector contributes significantly to these emissions. READ MORE

  3. 3. Development of fine-mesh methodologies for coupled calculations in Light Water Reactors

    Author : Klas Jareteg; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; CFD; Coupled neutronics thermal-hydraulics; nuclear reactor multiphysics; multiphase flow;

    Abstract : This thesis presents fine-mesh multiphysics methodologies and algorithms for numerical predictions of the behavior of Light Water Reactor (LWR) cores. The multiphysics aspects cover the distribution of neutrons, the fluid flow of the coolant and the conjugate heat transfer between the solid fuel pins and the fluid coolant. READ MORE
