Fluids, Meteorology and Symmetry Group

Fluid Dynamics is the study of fluid motion (liquids, gases, and plasmas) and the forces exerted by the fluid on its surrounding.

Our group uses techniques such as asymptotic methods and large scale numerical simulations to model flows, along with more geometric ones such as geometric mechanics for example to model various types of flows.

The types of geometries that are encountered in the problems studied by this group include differential, symplectic, Kähler, algebraic and discrete.


The themes from this group range from fluid stability problems and vortex modelling on both small and large scales to the study of conservation laws and geodesic flows. Fluid dynamics applications of these research themes include predicting weather and climate systems, modelling turbulence, investigating fluid transport problems, modelling complex fluid flows and plasma modelling.

Further geometric mechanics applications are to the stability, bifurcations, dynamics and numerics of Lagrangian and Hamiltonian ODEs and PDEs, to non-Hamiltonian perturbations.

The group includes academics who are involved in cross-disciplinary research projects such as environmental fluid flows (with the Centre for Environment and Sustainability) and data assimilation in weather prediction (with the National Centre for Earth Observation).
