Overview of new MAST physics in anticipation of first results from MAST Upgrade Open
The mega amp spherical tokamak (MAST) was a low aspect ratio device (R/a = 0.85/0.65 ~ 1.3) with similar poloidal cross-section to other medium-size tokamaks. The physics programme concentrates on addressing key physics issues for the oper…

Multi-code analysis of scrape-off layer filament dynamics in MAST Open
Four numerical codes are employed to investigate the dynamics of scrape-off layer filaments in tokamak relevant conditions. Experimental measurements were taken in the MAST device using visual camera imaging, which allows the evaluation of…

3D Simulations of Scrape-Off Layer Filaments Open
In the Scrape-Off Layer (SOL) of magnetic confinement devices, cross-field transport of particles is dominated by the convection of filamentary plasma structures via self-generated E×B velocity fields. This thesis investigates the dynamics…

Blob dynamics in the TORPEX experiment: a multi-code validation Open
Three-dimensional and two-dimensional seeded blob simulations are performed with five different fluid models, all based on the drift-reduced Braginskii equations, and the numerical results are compared among themselves and validated agains…

Investigation of the effect of resistivity on scrape off layer filaments using three-dimensional simulations Open
The propagation of filaments in the Scrape Off Layer (SOL) of tokamaks largely determines the plasma profiles in the region. In a conduction limited SOL, parallel temperature gradients are expected, such that the resistance to parallel cur…

The effects of shape and amplitude on the velocity of scrape-off layer filaments Open
A complete model of the dynamics of scrape-off layer filaments will be rather complex, including temperature evolution, three dimensional geometry and finite Larmor radius effects. However, the basic mechanism of ExB advection due to elect…

Investigation of the Effect of Collisionality on Scrape Off Layer Filaments using Three Dimensional Simulations Open
The propagation of filaments in the Scrape Off Layer (SOL) of tokamaks largely determine the plasma profiles in the region. Reactor relevant conditions will require interactions between neutrals and plasma in the divertor region to mitigat…
