The MHD Thin Shell Equations - studying basic properties of waves, instabilities and turbulence
In many astrophysical and geophysical situations of interest, turbulent interactions take place within a thin layer of stably stratified fluid in the presence of a magnetic field. Examples of such situations may include the outer layers of exoplanets or the interiors of stars - for example the solar tachocline.
Such dynamics may be modelled using the thin-shell MHD equations where a reduced model system is derived asymptotically. The properties of these equations has only recently begun to be investigated. This project is to derive basic properties of waves, instabilities and turbulence in such a system and compare with more complicated models. This research is to be carried out in the Astrophysical and Geophysical Fluid Dynamics research group, which is one of the largest such research groups in the world
This project is open to self-funded students and UK/EU students are eligible for funding from the STFC Doctoral Training Partnerships. All students (worldwide) are eligible for funding through the ERC project `Direct Statistical Simulation of the Sun and Stars'; these 3.5 years scholarships cover the cost of fees and provide a maintenance grant matching the Research Council UK rate (£14,553 for 2017/18).
