  2. 6. Gyrokinetic simulations of turbulent particle and heat transport in tokamaks

    Author : Daniel Tegnered; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tokamak; plasma physics; turbulence; transport; gyrokinetics; TEM; ITG; impurities; fusion; Joint European Torus;

    Abstract : Fusion power is one of few viable sustainable means of energy production. The tokamak is arguable the most mature technology to magnetically confine fusion plasmas. In these devices, heat and particle transport is dominated by small-scale turbulent fluctuations. READ MORE

  4. 7. Turbulent impurity transport in tokamak fusion plasmas

    Author : Andreas Skyman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tokamaks; fluid theory; ion temperature gradient mode; impurity transport; trapped electron mode; fusion plasma physics; turbulence; e-science; Joint European Torus; gyrokinetic theory;

    Abstract : With the enormous growth of high performance computing (HPC) over the last few decades, plasma physicists have gained access to a valuable instrument for investigating turbulent plasma behaviour. In this thesis, these tools are utilised for the study of particle transport in fusion devices of the tokamak variety, focusing in particular on the transport of impurities. READ MORE

  5. 8. Simulation and assessment of particle transport in fusion plasmas

    Author : Emil Fransson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fusion -- Plasma physics -- Turbulent transport --Gyrofluid --Gyrokinetic;

    Abstract : A civilized society need energy to function. An attractive new energy source is nuclear fusion with its abundance of fuel, intrinsic safety and limited environmental impact. Although the concept of fusion for energy has been well understood for over a century, to create it here on earth has been more irksome. READ MORE

  6. 9. Turbulent transport in tokamak plasmas: linear-, quasi- and non-linear simulations

    Author : Emil Fransson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion – Plasma physics – Turbulent transport – Gyrofluid – Gyrokinetic;

    Abstract : An attractive energy source is nuclear fusion with its abundance of fuel, intrinsic safety and limited environmental impact. Although the concept of fusion energy was established in the 1920s, to develop fusion as an energy source has been challenging. READ MORE

  7. 10. Turbulent and neoclassical transport in tokamak plasmas

    Author : Istvan Pusztai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Abstract : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. READ MORE
