1. Simulation and assessment of particle transport in fusion plasmas
Sammanfattning : 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. LÄS MER
2. Turbulent and neoclassical transport in tokamak plasmas
Sammanfattning : 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. LÄS MER
3. Experimental study of bubble dynamics and transport
Sammanfattning : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. LÄS MER
4. Collisional transport in edge transport barriers and stellarators
Sammanfattning : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. LÄS MER
5. Residues from biochemical production of transport biofuels in Northern Europe : combustion properties and applications
Sammanfattning : Residues from biochemical production of liquid transport biofuels will probably become available for energy use if more gasoline and diesel is substituted. For processes used in northern Europe they amount to 35-65 % of the feedstock energy and despite interest from energy companies, their fuel properties are largely unknown. LÄS MER
