Research summary:

My research involves the theoretical/numerical modelling of fluid systems in the presence of rotation, magnetic fields, and shear flows. To do this I use various numerical techniques (and computer power) to solve the equations relevant to fluid dynamics and magnetic field generation. My research has applications to Earth's core, the Sun's atmosphere, planetary atomspheres, protoplanetary discs, and other astrophysical objects.

This research is primarily motivated by a desire to better understand the fluid dynamics - including convection processes - and magnetic field generation - the 'dynamo process' - within planets and stars. In particular, numerical simulations are able to provide insight into the dynamics of the chaotic fluid regions (e.g. Earth's liquid iron outer core, the solar convection zone, planetary atomspheres) where magnetic fields are generated.

I am currently interested in taking on more PhD students. If you are a prospective PhD student and would like to know more about the projects below, then please get in touch with me: Robert.Teed@glasgow.ac.uk

Potential PhD projects:

  • Modelling the force balance in planetary dynamos.
    Current simulations of magnetic field (the 'dynamo process') generation in planets are run, not under the conditions of planetary cores and atmospheres, but in a regime idealised for computations. To forecast changes in planetary magnetic fields such as reversals and dynamo collapse, it is vital to understand the actual fluid dynamics of these regions. The aim of this project is to produce simulations of planetary cores and atmospheres with realistic force balances and, in doing so, understand how such force balances arise and affect the dynamics of the flow. The importance of different forces (e.g. Coriolis, Lorentz, viscous forces) determine the dynamics, the dynamo regime, and hence the morphology and strength of the magnetic field that is produced. This project would involve working with existing numerical code to perform the simulations and developing new techniques to determine the heirarchy of forces at play.
Force balance of a weak field dipolar dynamoForce balance of a strong field dipolar dynamoForce balance of a fluctuating multipolar dynamo
  • Identifying waves in dynamo models.
    This project would involve using existing (and developing new) techniques to isolate and study MHD waves in numerical calculations. Various classes of waves exist and may play a role in the dynamo process and/or help us better understand changes in the magnetic field.

  • The effects of magnetic fields on zonal flows in planetary interiors.
    This project would involve analytical and numerical solutions of equations governing (magneto)convection in simplified geometries. For example, the Jovian atmosphere can be modelled using plane or annular geometries which simplfy the solutions to the governing equations. The aim would be to better understand how a magnetic field can affect the jets of Jupiter's atmosphere.
  • Modelling the solar dynamo and solar cycle.
    This project would use simulations to look at the roles shear flow and helicity could play in generating the Sun's magnetic field and producing the 11-year solar cycle.
