Global simulations of heat-flux-driven buoyancy and magnetothermal instabilities, and their astrophysical implications
… plasma. We simulate the magneto-thermal instability (MTI), and the heat-flux-driven buoyancy instability (HBI) in two- and three- dimensional, global hydrodynamic simulations performed by the AREPO code, and verify the results of previous works. Our results have important astrophysical …

Shearing waves and the MRI dynamo in stratified accretion discs
… magnetic field via the magnetorotational instability (MRI) which would be a source of dissipative turbulence. Previous local simulations of the MRI have shown that the dynamo changes character on addition of vertical stratification. We investigate numerically 3D hydrodynamic shearing waves …

Experiments on the dynamics of buoyancy-driven flows in reactive porous media
… In these situations of slow flow, the effects of buoyancy may become important. Understanding these flows is important in a number of new industrial applications, such as geological disposal of nuclear waste. In this thesis, a series of new experiments are presented investigating the phenomena …
