  1. 36. Beam Momentum Changes due to Discharges in High-gradient Accelerator Structures

    Författare :Andrea Palaia; Volker Ziemann; Bernhard Holzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The key questions left unanswered by the Standard Model, and the recent discovery of a Standard Model-like Higgs boson, demand an extension of the research on particle physics to the TeV energy scale. The Compact Linear Collider, CLIC, is a candidate project to achieve such goal. LÄS MER

  3. 37. Air-Sea Exchange of Momentum and Sensible Heat Over the Baltic Sea

    Författare :Xiaoli Guo Larsén; Sven-Erik Gryning; Uppsala universitet; []
    Nyckelord :Meteorology; meteorologi;

    Sammanfattning : Long term measurements are used to explore the wave impact on the momentum and sensible heat transfer in the marine atmospheric surface layer. This is important in determining the boundary conditions of atmosphere-ocean coupled models of many scales. LÄS MER

  4. 38. Studies of small momentum transfers in high energy hadron-proton elastic scattering

    Författare :Leif Gustafsson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : .... LÄS MER

  5. 39. Solid Oxide Fuel Cell Modeling at the Cell Scale - Focusing on Species, Heat, Charge and Momentum Transport as well as the Reaction Kinetics and Effects

    Författare :Martin Andersson; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOFC; anode-supported; modeling; CFD; charge species heat momentum transport; electrochemical internal reforming reactions; TPB; area-to-volume ratio; COMSOL Multiphysics;

    Sammanfattning : Fuel cells are electrochemical devices that directly transform chemical energy into electricity. They are promising for future energy systems, since they are energy efficient, able to use renewable fuels and, when hydrogen is used as fuel, there are no direct emissions of greenhouse gases.

  7. 40. Continuum modeling of the coupled transport of mass, energy, and momentum in paperboard

    Författare :Henrik Askfelt; Hållfasthetslära; []
    Nyckelord :Paperboard; Mixture theory; Porous media; Large strains;

    Sammanfattning : This thesis investigates the coupling between moisture, heat, and deformation in paperboard. The presented investigations are primarily conducted via macroscale continuum modeling but experimental characterisations are also made. LÄS MER
